Matt Zwolinski of Bleeding Heart Libertarians has written an excellent series of posts on the libertarian justification of property rights. Here‘s the latest.
The first and most important thing to note about both Locke and Nozick’s arguments is that, unlike utilitarian arguments, they are individualistic rather than collectivistic in nature. For the utilitarian, all that matters in justifying an action (or an institution like property rights) is its effect on overall well-being. On the utilitarian view, then, property rights are justified if the overall benefits they produce are greater than the overall harms they produce, regardless of how those benefits and harms are distributed among different individuals.
For Locke and Nozick, on the other hand, property rights are only justified if they benefit (or at least do not harm) each and every individual. Now, this probably seems like an extremely tough argumentative hurdle for the defender of property to clear. Could it really be the case that each and every individual is better off under a system of private property rights than he would have been without one?
The answer is, or can be, yes. Almost everyone today is vastly better off, and freer, because of the system of private property rights. In those rare, possibly pathological cases in which a person is worse off due to the system of property rights, the Lockean justification of property rights provides a rationale for some kind of “re”distribution as a matter of justice, a point that Matt notes at the end but defers to a future essay. In the event, this is one area where I tend to agree with BHL’ers: there should be a basic income of sort to replace the welfare state, which would probably have to be set at a few thousand dollars a year in the present-day United States in order to ensure that literally everyone is better off due to the private property system, despite its coercive nature.
