ABSTRACT
One distinctive feature of libertarianism is its position on property rights. Libertarians differ amongst themselves on the extensiveness of natural property rights: While left-libertarians hold that external resources may only be appropriated on an egalitarian basis, right-libertarians typically adopt a weaker construal of the constraints on appropriation, for example, Nozick's view that appropriation must not worsen the situation of others. While libertarians will surely find the hybrid theory's conception of natural property too weak, those left-liberals who endorse pure conventionalism will press a different kind of objection. An occupancy right comprises two main elements: First, a liberty to reside permanently in a particular geographical space and to make use of that space for social, cultural, and economic practices. Second, a claim-right against others not to remove one from that area, to allow one to return to it, and not to interfere with one's use of the space in ways that undermine the shared social practices in which one is engaged.
