 Weakened conceptions of self-ownership, however, raise important questions. For one, if self-ownership turns out to have multiple dimensions that can be weakened in light of competing considerations, it loses some of its theoretic appeal. After all, part of that appeal was the idea’s relative simplicity, which seemed to make it a good starting point for a theory of justice. Once we start trading off the idea against other considerations, those considerations are thereby admitted into the libertarian moral universe. This raises complicated questions about their relative weights, appropriate trade-off rules, and so on.
