I think "completely different" is overstating it. If the paternalistic instinct is to say people who sell body parts are prone to abuse, certainly the same can be said about prostitution. Similarly, if the average person is ill equipped to gauge risks and bear the consequences of poor risk management, then the calculus applies in sex (STIs, pregnancy, rape, etc.) and in organ donation. Though the most interesting organ-based financial instruments would be rights to harvest organs post mortem, which several people in this thread seem to be overlooking. And no matter how intellectually satisfying it would be if it were true, I don't think Western culture (or psychology in general) agrees with you that sex is just another service like computer repair. We don't have special categories of crimes for forced computer repair at gunpoint for instance. And we don't shame and fire overbearing bosses for pressuring employees into illicit computer repair.
