"If you read more carefully, you'd have noticed that I stated that. I'm discussing morality, not US law"
You seem to misundertand both US law and morality. It is not immoral to regulate radio spectrum so that it can be used to the greatest benefit of society.
Oh, thanks for clearing that up. I notice you haven't proven your assertion, but I'm happy to take your word for it. But I think even more is true. It's moral for the government to regulate all land in the US, and all labor as well, to the greatest benefit to society. In fact, all factors of production should be regulated to the greatest benefit of society. I certainly hope you agree, comrade.
