 Many have argued that some things should not be for sale (Anderson 1993; MacDonald &amp; Gavura 2016; Sandel 2012; Satz 2010). Among the things commonly said to be inappropriate for sale are sexual services, surrogacy services, and human organs. Some writers object to markets in these items for consequentialist reasons. They argue that markets in commodities like sex and kidneys will lead to the exploitation of vulnerable people (Satz 2010). Others object to the attitudes or values expressed in such markets. They claim that markets in surrogacy services express the attitude that women are mere vessels for the incubation of children (Anderson 1993); markets in kidneys suggest that human life can be bought and sold (Sandel 2012); and so on. (For a discussion of what it might mean for a market to “express” a value, see Jonker [2019].)
