The power to prevent others from copying the arrangement is an incentive to arrange in the first place. But it should be limited. Property rights allow me to restrict your speech when your literally on my government sanctioned land. I don't see much difference when it comes to IP.

Edit: copyright should be more limited than physical property rights, so I'm in agreement. But neither can be absolute when the government only has a piece of paper to abide by that prevents them from being revoked.
