I had a good spat with (R.) Dan and Shmuel over facebook about the uses and disadvantages of organ trafficking. They raise important concerns regarding a persons ability to consent (well, that might be putting words in their mouths), lowering of costs of organs and generally saving people's lives. I worry about people's ability to consent and exploitation of the poor.
If people are 'fairly' compensated for their organs, why shouldn't they be allowed to sell them on the market?
