I don't see how it's not coherent to think that something that is allowed should be allowed for everyone, but that something that isn't allowed shouldn't be except if you get permission. If someone thinks that the Internet should be a public network, it seems reasonable for them to also think that you shouldn't be able to exclude someone from using it in a way that is legal for anyone else. You might think differently, but I don't see how their position wouldn't be coherent.
