It doesn’t account for how we can come to own both the parts of something we have mixed our labor with and the parts we haven’t. How is it possible that in owning property—which first became a commodity because someone improved it—one comes to own the mineral rights to that property? Also, how do we decide when something is too big to mix our labor with, so that we cannot, as in Nozick’s ocean example, come to own all of it?
