Many scholars, activists, and officials oppose decriminalization. First, some people argue that criminal penalties do not violate rights because people do not have rights to buy or sell sex. Others object that decriminalization would increase the prevalence of sex work, which is worse than other jobs, and so paternalistic limits on the industry are justified. Another set of objections presses the claim that the sex industry has negative externalities, such as increased rates of sexual transmission of disease, human trafficking, rape, or crime. Finally, some claim that a decriminalized sex industry would exacerbate existing economic or social inequalities. This chapter shows that these objections do not succeed in justifying alternatives to decriminalization.
