May you sell your vote? May you sell your kidney? May gay men pay surrogates to bear them children? May spouses pay each other to watch the kids, do the dishes, or have sex? Should we allow the rich to genetically engineer gifted, beautiful children? Should we allow betting markets on terrorist attacks and natural disasters? Most people shudder at the thought. To put some goods and services for sale offends human dignity. If everything is commodified, then nothing is sacred. The market corrodes our character. Or so most people say. In Markets without Limits, Jason Brennan and Peter Jaworski give markets a fair hearing. The market does not introduce wrongness where there was not any previously. Thus, the authors claim, the question of what rightfully may be bought and sold has a simple answer: if you may do it for free, you may do it for money. Contrary to the conservative consensus, they claim there are no inherent limits to what can be bought and sold, but only restrictions on how we buy and sell.

Jacob Sparks critiques our recent work on commodification by arguing that purchasing love indicates one has defective preferences. We argue A) it is possible to purchase these things without having defective preferences, B) Sparks has not shown that acting such defective preferences is morally wrong, C) that Sparks’ misunderstands the Brennan–Jaworski Thesis, and so has not produced a counterexample to it, and finally D) that when we examine the processes by which love is gifted, it is unclear whether these processes should be preferred.

We aim to show anti-commodification theorists that their complaints about the scope of the market are exaggerated. There are we agree things that should not be bought and sold but that’s only because they are things people shouldn’t have or do or exchange in the first place. Beyond that we argue there are legitimate moral worries about how we buy trade and sell but no legitimate worries about what we buy trade and sell. In almost every interesting case where they have argued markets are morally impermissible on the contrary we argue such markets are permissible. Where they see the market as having a fundamentally amoral ethos or as tending to corrupt us we see it as moral and morally ameliorative. Where they think the solution is to contract the market we think the solution is to expand it.

This paper argues that mandatory, government-enforced vaccination can be justified even within a libertarian political framework. If so, this implies that the case for mandatory vaccination is very strong indeed as it can be justified even within a framework that, at first glance, loads the philosophical dice against that conclusion. I argue that people who refuse vaccinations violate the ‘clean hands principle’, a moral principle that prohibits people from participating in the collective imposition of unjust harm or risk of harm. In a libertarian framework, individuals may be forced to accept certain vaccines not because they have an enforceable duty to serve the common, and not because cost–benefit analysis recommends it, but because anti-vaxxers are wrongfully imposing undue harm upon others.
