I don't like that the author lumps in IP monopolies with property rights. They are fundamentally different concepts. Some of the examples cited deal with actual property, such as power transmission lines or shared oil fields. But patents and copyright deal with IP, which has a whole different set of expectations and ramifications. Still, the author's conclusion seems sound to me: the next time we start handing out new ownership rights—whether via patents or copyright or privatization schemes—we’d better try to weigh all the good things that won’t happen as a result.
