Any substantive notion of self-ownership presupposes well-defined property rights over external resources. Left-libertarians usually limit this category to natural resources. I argue that in a specialized economy, substantive selfownership equally needs to be complemented by a definition of property rights to the cooperative surplus. The natural way for left-libertarianism to provide such a definition is to view the cooperative surplus as an external resource and to distribute it equally. The second part of the article makes the general point that a complete theory of justice needs to take a stance on distribution in various contexts. Articulating the differences between these contexts allows us to gain a better understanding of how left-libertarianism relates to other theories of justice.
