 Others interpret the Lockean proviso as requiring something like a sufficientarian requirement, such that people must have access to an adequate share of natural resources (Lomasky 1987; Wendt 2017). This view might invoke differing conceptions of adequacy, such as well-being or the ability to be self-governing (as in Simmons 1992, 1993). Or one might see the proviso as ensuring the ability to exercise one’s rights of self-ownership (Mack 1995).
