In several works, Jason Brennan and Peter Martin Jaworski defend the following thesis: If it is permissible to have, use, or exchange something for free, then it is permissible to have, use, or exchange that thing for money. In this paper, I argue that No Limits is false. Moreover, the reasons why it is false reflect many of the complaints made against markets. The paper will proceed as follows: In §1, I summarize Brennan and Jaworski’s position to clarify exactly what (...) a challenge to No Limits requires. In §2, I raise just such a challenge, one which also captures the concern behind some “semiotic objections.” In §3, I offer a modification to No Limits that avoids my objection but, as a result, re-opens the question of whether markets in some of the goods Brennan and Jaworski discuss are permissible. I conclude in §4 by considering a possible response and some thoughts on the dialectic as it stands. (shrink)

In Markets Without Limits and a series of related papers, Jason Brennan and Peter Jaworski argue that it is morally permissible to buy and sell anything that it is morally permissible to possess and exchange outside of the market. Accordingly, we should open markets in “contested commodities” including blood, gametes, surrogacy services, and transplantable organs. This paper clarifies some important aspects of the case for market boundaries and in so doing shows why there are in fact moral limits to the (...) market. I argue that the case for restricting the scope of the market does not turn on the idea that some things are constitutively non-market goods; it turns instead on the idea that treating some things according to market norms would threaten the realization of particular kinds of human interests.
