The typical method of acquiring a property right involves transfer from a previous owner. But sooner or later, that chain of transfers traces back to the beginning. That is why we have a philosophical problem. How does a thing legitimately become a piece of property for the first time ? In this essay, I follow the custom of distinguishing between mere liberties and full-blooded rights. If I have the liberty of doing X , then it is permissible for me to (...) do X . But the mere fact that I am at liberty to do X leaves open the possibility that you might be at liberty to interfere with my doing X . Accordingly, liberties are not full-blooded rights, since my having a right to do X has the additional implication that others are not at liberty to interfere with my doing X . When it comes to mere liberties, interference is not a violation. You can violate rights, but you cannot violate liberties. (shrink)

According to the negative principle of appropriation a person can acquire an unowned resource if doing so respects a certain condition (the Lockean proviso). Contrary to some views, a proviso of this sort is not incompatible with libertarianism. Moreover, no unilateral powers of acquisition can fail to consider the impact on the interests of others. Hence, a doctrine of appropriation must incorporate such a proviso. However, the several interpretations such a proviso can take on various dimensions will be either implausible (...) as a way of taking into consideration the interests of others, or unable to generate the kind and extent of property rights libertarians typically endorse.

Ecosystem services are the benefits people obtain from ecosystems. Many of these services are provided outside the borders of the land where they are produced. This article investigates who is entitled to these non-excludable ecosystem services from a libertarian perspective. Taking a right-libertarian perspective, it is concluded that the beneficiaries generally hold the right to use non-excludable ecosystem services and the right to landowners not converting ecosystems. Landowners are only at liberty to convert ecosystems if they appropriated their land before (...) any beneficiary used the services and converted the ecosystems before or shortly after the beneficiaries started using the services. This means that the beneficiaries generally hold the right to compensation payments by the landowners in the event of service losses, instead of the landowners holding the right to payments for ecosystem services by the beneficiaries. Taking a left-libertarian perspective, it is concluded that landowners ought to pay for the non-excludable ecosystem services lost as a result of their activities as well as beneficiaries paying for the non-excludable ecosystem services they use. These payments are not made mutually, however, but to a central authority that distributes the returns to the community on an equal per capita basis. (shrink)

Sufficientarian libertarianism is a theory of justice that combines libertarianism’s focus on property rights and non-interference with sufficientarianism’s concern for the poor and needy. Persons are conceived as having stringent rights to direct their lives as they see fit, provided that everyone has enough to live a self-guided life. Yet there are different ways to combine libertarianism and sufficientarianism and hence different types of sufficientarian libertarianism. In the article I present and discuss three types, and I argue that the last (...) one overcomes the problems of the other two. The first type combines libertarianism with a sufficiency principle in what is sometimes called the ‘ethics of distribution’. The second incorporates modest welfare rights into a libertarian theory of justice. The third endorses a sufficientarian Lockean proviso for practices of private property within a libertarian theory of justice. I argue that it is superior to the others. (shrink)

Recently, Eric Mack, Edward Feser, and Daniel Russell have argued that self-ownership justifies a constraint on the use of property such that an owner’s use of property may not severely negate the ability of others to interact with the world. Mack has labeled this constraint the self-ownership proviso. Adopting this proviso promises right-libertarians a way of avoiding the extreme implications of a no-proviso view, while maintaining a consistent and cohesive position. Nevertheless, I argue that self-ownership cannot ground the constraint on (...) property use that Mack, Feser, and Russell think that it can. (shrink)

: This paper argues for the consistency of adverse possession in land with a strict Lockean-liberatarian understanding of property rights due to the impermanence of man-made improvements by which unowned property is originally appropriated. This approach to property rights reconciles left- and right-libertarian positions as end points on a continuum of “temporal attitudes” toward property retention. ….
