Distributive justice, best options and organ markets: a reply to Semrau

How important is it, morally speaking, that banning the sale of organs removes the best option available to would-be organ sellers? According to a widespread argument called the best option argument, this is very important. In a recent article I criticised such reasoning, drawing on considerations of distributive justice. Luke Semrau has argued that I have misunderstood the best option argument. In this article, I respond to Semrau's criticism and elaborate on my original argument.
