The state is involved in creating [intellecutal-property based] monopolies, because there are choices to be made in designing property systems. Lots of them, in fact. One can agree with the idea that there should be intellectual property rights without answering the question "How far should those rights stretch? What conditions should Microsoft be able to attach to its software licenses? Restraints on competition? On criticism? To get the benefits of the state property grant, should it have to make source code available under a compulsory license? Should it be able to use copyright law to restrict its competitors from making "interoperable" products?"
