 Whatever interpretation of the proviso one accepts, however, libertarians left and right agree that once persons enjoy legitimate rights over their property, these are more or less immune to other claims of distributive justice. There is little room in the theory for thinking that certain distributions or material outcomes are morally significant as such. To the libertarian, concerns such as material equality are inconsistent with an appropriate concern for people’s equality. (See, e.g., Schmidtz 2006.) Thus, Nozick (1974) argues in his famous discussion How Liberty Upsets Patterns that because any system of property must allow gifts and other voluntary transfers, and because these will significantly upset whatever distribution is put in place, there is very limited room for concerns with distributional equality. Since treating people as moral equals means respecting them as the holders of these rights, and since such rights will be exercised in ways that will not equalize material outcomes, forced redistribution counts as unjust.
