Buying human kidneys: autonomy, commodity and power.

Buttle's reply to my objections to buying kidneys is helpful but unconvincing in two respects. Doing something freely leaves quite open the possibility that one is thereby making a commodity of a person; and the effects of institutionalising such a practice is itself a matter for concern. And while his emphasis on 'power' is important, the concept is hardly less problematic than 'commodification'.
