 Libertarian theory can thus be defended in many different ways. This is true both of theories that give pride of place to self-ownership and of theories that don’t. Examples of the former include Eric Mack (2002, 2010) who sees self-ownership rights as among several natural rights grounded in our nature as purposive beings. In Mack’s view, the protections and freedoms offered by the idea are justified in order to grant to all individuals a separate sphere in which they can act in accordance to their self-chosen purposes. Similarly, Loren Lomasky (1987) derives rights from a related, although slightly different, conception of people as project pursuers. John Tomasi (2012) argues that strong rights over our bodies are required by the ideal of democratic legitimacy. According to Daniel Russell (2018), self-ownership rights provide the only way that people who live together can all genuinely live their own lives.
