The idea of property as legitimate is pretty much arbitrary - others have indeed come out on the other side of the fence: Considering the enforcement of property rights to land akin to theft (e.g. Proudhon) or illegitimate use of force, on the simple premise that it deprives others of use of a shared resource.
The libertarian fetish for accepting the use of force to protect one arbitrary artificial construct as somehow critical to liberty, while rejecting the use of force to protect other artificial constructs strikes me at the same time as deeply comical, and ridiculously hypocritical on the other.
