⁵ See Narveson, Jan, “Original Appropriation and Lockean Provisos,” Public Affairs Quarterly 13, no. 3 (1999): 205–27, at 214–15Google Scholar, who says that it is possible to read the proviso more narrowly as a ban on interfering with the use of extrapersonal goods already underway. But this strikes me as a theory of property—viz. that engaging with some such good is sufficient to gain title to it—rather than a constraint on property. In any case, even Narveson (p. 222) acknowledges that the “original intent” of the proviso has to do with fair shares.

³⁶ And this is exactly what Narveson (“Original Appropriation,” 219) says: “given liberalism, we do not primordially own the world—only ourselves. And even that isn't primordial. We must argue even for that.” That is why Narveson can no longer hold the view that “a right to our persons as our property is the sole fundamental right there is”; see Narveson, Jan, The Libertarian Idea (Philadelphia, PA: Temple University Press, 1988), 66Google Scholar; emphasis in the original.

³⁷ Narveson, “Original Appropriation,” 219. Here he fares better than Rothbard (The Ethics of Liberty, 99–100), who holds that parents own their children, although this ownership must be temporary and of a “trustee” sort, since “it surely would be grotesque for a libertarian who believes in the right of self-ownership to advocate the right of a parent to murder or torture his or her children.” Fair enough, but of course the whole question is whether children are self-owners in the first place.

⁵⁸ This strong separation of self-ownership and extrapersonal ownership is particularly clear in Vallentyne, Peter, Steiner, Hillel, and Otsuka, Michael, “Why Left-Libertarianism Is Not Incoherent, Indeterminate, or Irrelevant: A Reply to Fried,” Philosophy and Public Affairs 33, no. 2 (2005): 201–15, at 201, 208–9CrossRefGoogle Scholar, who note that the egalitarian dimension of left-libertarianism is distinct from its libertarian dimension (i.e., self-ownership), and that these two dimensions are based on respect for the moral status of different things (things and persons, respectively).

⁵⁹ This amounts to what Vallentyne (“Libertarianism”) calls “unilateralist” left-libertarianism. I shall not discuss the non-unilateralist alternative of joint world ownership, since it is generally—and, I think, rightly—held to be inconsistent with self-ownership; see, e.g., Cohen, G. A., Self-Ownership, Freedom, and Equality (Cambridge: Cambridge University Press, 1995)CrossRefGoogle Scholar; Mack, “Self-Ownership, Marxism, and Egalitarianism, Part II,” 243–44, 250–51; and Vallentyne, “Libertarianism.” For a dissenting view, see Jedenheim-Edling, Magnus, “The Compatibility of Effective Self-Ownership and Joint World Ownership,” Journal of Political Philosophy 13, no. 3 (2005): 284–304CrossRefGoogle Scholar.

⁶⁰ We can therefore set aside Steiner's worries (An Essay on Rights, 249–61) about giving a Hohfeldian analysis of the right of bequest as a right of deceased persons; for even if there turned out to be no such thing as a right of bequest, it would follow only that one could not make compensation for removing goods from the commons by giving up that right. It would not show that no such compensation is called for.

⁶⁸ To put this another way, a world in which ownership is constrained by agent-neutral welfarist values is not safe for self-owners.
