I am actually up for a free market for organs, because of the precise reasons that you cite, provided that there are some safeguards. The hospitals should provide services that talk about the health risks involved and psychological counseling. I bet, if this kid got a 30 minute talk about the relative importance of the iPad2 vs the kidney, he would have changed his decision. Then again, some are so poor that they do need the money for their families, so these should get the maximum rate.

This are a lot of ethical, economical, and operational questions related to this. Doesn't mean that it should be banned, though.
