Establishing the validity of the Social Contract
It is sometimes said that all right are property rights stemming from the ownership of one's own body. From ownership of one's body and therefore labour, the homestead principle is derived.
In Anarchist-Capitalist circles the Homestead principle is well regarded and used as support for perpetual land ownership.
It is also accepted in An-Cap circles that the Social contract is invalid, but it isn't rally that hard to justify the social contract using the concept of perpetual land ownership as the justification.
If on one hand the “mixing of labour” (a transitory event) permanently changes the nature of land and all succeeding individuals are bound by that, then why is it not possible in a general societal sense to say the same.
Rephrased the Homesteading principle could be expressed as “You have no right to use this land or these resources as I have previously claimed them”, the social contract “You have no right to protest about or change the current allocation of resources as the rules are well established”. Not dissimilar when stated in that way.
Not only are they not dissimilar in function but the perpetual homesteading principle can be used to support the social contract and therefore the state once a few facts are added to the mix. In all countries that I know about the government is used as the repository and arbiter of title to land, simply said this means that the State determines who is practically able to use the land in question. In principle there is nothing wrong with this relationship and if you add the concept of perpetual land ownership via homesteading you have a reason for the existence of states. If a homesteader can determine the current and future use of their land then if the homesteader enters into an agreement with a third party to protect that land and determines that all future inheritors can only own the land if they accept that agreement then you have the justification for a kind of state. As time passes and the current owners surrender more of their “ownership privileges” to the state there is no sound justification for opposing this. And so the unlimited state and the social contract stem from the unlimited and perpetual ownership of land.
So if you derive a concept of perpetual ownership of land from the principle of homesteading, then you are bound by your own logic to accept the state.
