 Other writers criticize these arguments, and in general, the attempt to “wall-off” certain goods and services from markets. Brennan and Jaworksi (2016) object to expressive or “semiotic” arguments against markets in contested commodities (cf. Brown &amp; Maguire 2019). Whether selling a particular thing for money expresses disrespect, they note, is culturally contingent. They and others (e.g., Taylor 2005) also argue that the bad effects of markets in contested commodities can be eliminated or at least ameliorated through appropriate regulation, and that anyway, the good effects of such markets (e.g., a decrease in the number of people who die because they are waiting for a kidney) outweigh the bad.
