Brainpolice:Is a fuedal landlord's dominion, even if it is considered to be "private" (in legal terms in particular), legitimate under a libertarian theory of justice in property? According to Rothbard, no, and the peasants have the moral authority to claim the fruits of their labor.
I wasn't thinking in terms of feudal landlords, but simply landlords. If I legitimately aquire a plot of land and build (or contract to have built) apartment complexes on said land, do I not have the right to charge my tenants rent? Do I not have the right to create and enforce rules for the use my property (pet policy, speed limits in the parking lots, noise restrictions, etc.)? My tenants of course have the right to claim the fruits of their labor. They also have the right to live somewhere other than in one of my apartments, and I have a right to insist they do if they break the rules one too many times or stop paying their rent.
This does not describe the typical state or monarchy, as there is choice involved. However, as in the case of Vatican City, it can be argued that private property can, in fact, result in a state, or at least something similar to a state.
