I am a conservative and capitalist in the greatest extreme possible within such parameters to still allow a nation state to sustain itself entirely.... having said that--- I believe in an individuals right to do basically everything they choose so long as their choices to not infringe nor procreate and environment inescapable of others who have the equal rights to live.

A person SHOULD have the right to sell any part of themselves so long as that person is of sound mind, coherent, premeditated thought process fulfilled and of an age appropriate in adulthood to fully understand the decision they are making. So yes, I think a person should be able to sell a body part.
