I disagree.
But here is what the Catholics have to say about human cloning.

Cloning: Ten Most-Asked
by Dr. Peter J. Riga
1999
What is cloning?
Cloning is the taking of the egg of a female of the species and removing its nucleus (DNA or genetic material). Then, the dormant DNA nucleus of a cell from another of the species is placed in the first cell and, by electric shock, reactivates the dormant DNA which then begins to multiply like a fertilized cell. No male participation is necessary and the reproduction process is or can be parthenogenic. The result will be an exact genetic and biological replica of the one who gave the DNA. Once thought to be impossible, it has now been done on sheep and monkeys. While the clone is identical to its paradigm, it is not totally so. A clones genome - its complete set of genetic material - would not be identical to its paradigm. Recombinant DNA creates a unique genome for each individual, even in those who have inherited DNA identical to another. Is cloning harmful? We do not know the long-term problems associated with this procedure because no empirical studies have been done. There are simply too few of these clones to produce such a study. What effects any human cloning might have is all speculative at the present time.
Can humans be cloned?
Scientists have already cloned monkeys which are primates and therefore biologically close to humans. There is no reason why humans cannot be cloned using the same procedures as in other mammals.
Will humans be cloned?
The answer to this question, for better or worse, is yes. No amount of legislation is going to outlaw this procedure. Besides, legislation in this area does not have a good track record. In vitro fertilization, surrogate motherhood, sperm and ova banks, etc., at one time or another were forbidden or regulated or considered wrong. The research went on anyway, either in privately funded research facilities or in countries where the process was not regulated. For example, the United States has no statute or regulation forbidding human cloning. Other countries do. Therefore, human cloning is almost inevitable in spite of any law seeking to regulate or forbid it. Cloning will be done here or abroad.
Human cloning is therefore technically possible today. There are arguments for going forward with this technology which are therapeutic in nature. A cloned human embryo, modified genetically or not, can become a therapeutic instrument. It could synthesize different molecules and furnish biological elements of replacement, etc. But to the question of why clone humans, the answer is very complex, more complex than just a desire to care and to cure. In such a technology there is the realization of very lively fantasies of mastery over human life, an identical duplicate of oneself, engendering (one hesitates to call it birth) of a person outside of sexual bi-polarity and the constraints of a double parenthood. We are really talking about another kind of human condition. No birth, no parents, no real incarnation of flesh before, during and after birth. This may have ominous effects on the person cloned.
Can animal cloning be beneficial?
More research needs to be done in this area and both biologists and ethicists agree that such research should go forward. Such cloned genetics in animals is thought to be able to produce better livestock, disease resistance, better quality meat and more plentiful milk, etc., from genetically cloned species from the DNA of prize animals. In addition, better research on animals for human benefit will be advisable because there will be no variety in such animals used for human testing. Cloned animals may also be important sources for drugs and a medium for transplants in humans. For example, pigs can be cloned in such a way as to better transplant their organs for humans or for better production of insulin. The future in this area is full of promise so that research in the animal area should go forward.
Are there any benefits to human cloning?
It is hard to think of any which would not lead us into the dark recesses of eugenics, experimentation, partial birth abortion, dire effects on the cloned or simply vanity. The idea, for example, of replacing a dead child or parent or loved one by cloning a dying or dead person is grotesque. A person can never be replaced because each human person is a unique dignity. To clone for body parts (e.g. through partial birth abortion or after ten weeks gestation) is an abomination and murder, a denial of human rights. It is the use of a human being as a means and not an end. To clone a child for less intrusive, less invasive means may be ethical. For example, a live child or parent is dying of cancer and needs a unique bone marrow transplant. This may be a beneficial case which respects the dignity of the cloned child who will not be harmed by removal of bone marrow. This, of course, is speculative since the consent of the child is not and cannot be abolished. It would have to come from an independent and non-prejudiced source (e.g., a court).
Does a cloned person have a soul?
Of course. Just as children conceived in vitro have a soul. Moreover, cloned humans will be unique because of different influences on the child which comes from other sources in the environment. We are more than our genes. We are also a living, incarnate soul. While the genetic and biological direction of the clone and the paradigm will be identical, the different influences of culture, environment, other people, experiences of life, etc., will be different for each child, including a cloned child. We can already see this in the case of identical twins. While genetically from the same egg, they are essentially different in their personalities, having received different influences from their environments. In addition, the cloned person has an independent will and freedom as a person. A person is more than genetics and history; he or she is above all a spiritual entity with a soul.
Should humans be cloned?
Given that few, if any, benefits come from this biological process on humans, the only justification would be either vanity or curiosity. It will be done because it can be done a moral vacuity if there ever was one. These vanity reasons are not great enough moral justification for imposing a particular genetic and biological makeup on a child. If the process cannot be justified except for the most superficial reasons, then neither can it be morally justified. Neither would cloning be an improvement of the race which is a moral, not a genetic term. In morals, every person starts from zeroE irrespective of genetics.
What are the drawbacks of human cloning?
There are many the whole process is a pure process of science and technology. It is not the genesis of a human person within the context of love, but pure technology. Humans are specifically different from animals in that they are brought into the world by an act of love between two people, not of technology or instinct. Cloning reduces the person to a technological production and removes the clone from the love act at origins. The clone is made, not born. There may be deep problems in such a process if allowed to go forward.
Given that what we have in cloning is a species of parthenogenesis, the function of the father as role model, support and diversity becomes even more weakened that it is today. The sexuality of the sexes as diversity becomes irrelevant and we are introduced into the brave new world of technology, technique, and unlove. Cloning is a direct threat to the family. Even a childless couple who would clone one of the two would be the technological result of one or the other, not of their union in love. It would be an affair a un(e).
The temptation to the spare part syndrome will be very strong. We already take organs and brain cells from intentionally aborted fetuses for transplant into older humans (e.g. Parkinsons disease). Cloning will make this process perfect with no possible rejection in the paradigm from whom the DNA originally came. The temptation will be very great along with the further use of partial birth abortion for spare organs. Cloning is the technologizing of the whole human endeavor which turns out not to be human at all.
