 It is popular to label libertarianism as a right-wing doctrine. But this is mistaken. For one, on social (rather than economic) issues, libertarianism implies what are commonly considered left-wing views. And second, there is a subset of so-called “left-libertarian” theories. While all libertarians endorse similar rights over the person, left-libertarians differ from other libertarians with respect to how much people can appropriate in terms of unowned natural resources (land, air, water, minerals, etc.). While virtually all libertarians hold that there is some constraint on how resources can be appropriated, left-libertarians insist that this constraint has a distinctively egalitarian character. It might require, for instance, that people who appropriate natural resources make payments to others in proportion to the value of their possessions. As a result, left-libertarianism can imply certain kinds of egalitarian redistribution.
