This is an excellent start for a long discussion on economics, ethics, psychology, etc. that probably would be done better in a cafe, slowly sipping Earl Grey tea rather than on HN, but still.. One of the main points of the argument is that i) It is feared that the rich will take advantage if this is legalized ii) But the rich already have many ways of access to organs anyway iii) It is predominately the poor who die waiting for a kidney. This argument is strong, e.g. if Amit Gupta was a poor nobody, would his case get the exposure it did? On the other hand, isn't this argument similar to the one advocating free sale for guns, because criminals have access to these anyway and it's only the person on the street who gets hurt? I think the main argument against explicit sale of kidneys is on moral grounds, nor operational, i.e. how to best implement this system. You are selling part of your body, which no sane person in a normal situation would do, so there must be something wrong with this. This argument runs foul of the fact that other such activity, that is on similar gray (or really dark gray) area, is legal, e.g. prostitution, getting compensated for being a surrogate mother. Let's zoom on prostitution. You think it may be irrelevant to selling kidneys, but think about it: you are selling something to a stranger, kidney in one, dignity in the other, that normally you would not do. Many countries have legalized prostitution (http://en.wikipedia.org/wiki/Prostitution#Legality http://en.wikipedia.org/wiki/Prostitution#Legality) because of the realization that it is not the actual act that should be banned but all the bad secondary factors it brings, i.e. sexual slavery, veneral disease. If these can be controlled, why not make it legal between consensual parties. Still, this doesn't leave me feeling good, I feel an unease that I cannot put a finger as a human being. I feel similarly for selling organs.
