Question

Hello Rabbi,
Recently I was again thinking about the issue of kidney donation, and I came up with an idea that might perhaps address the broader problem of people waiting for transplants through legalizing organ trade in Israel. What do you think about that? (There is a Wikipedia article in English that expands a bit on the issue.)
At first glance, it seems to me that the main reason for rejecting the legalization of organ trade is to prevent the exploitation of people in financial distress who might be tempted to sell their organs. But what lies behind that argument is the assumption that kidney donation is an act that involves significant risk, and people in financial distress might be tempted without exercising judgment appropriate to the degree of risk. But nowadays the assumption of high risk is already less correct, in light of the development of modern medicine, which has made the process relatively quite safe.
