The best option argument and kidney sales: a reply to Albertsen.

In a recent article, Albertsen both elaborates and levels a justice-based objection to kidney sales. In the present article, I show that Albertsen has crucially misunderstood the best option argument. It is not a defence of kidney sales, as Albertsen claims. It is a reply to an objection. The objection, perennial in the debate, opposes kidney sales on the grounds that sellers would be harmed. The best option argument-proving that prohibitions tend to set back the interests of those denied their preferred option-shows this thinking to be confused. If sound, the best option argument dramatically undercuts any attempt to oppose a market citing would-be sellers' interests.
