Regulating broadcasts is only justified by the technical limitations of broadcasting: namely, that there's only so much spectrum to go around, so you must license out slots so they don't overlap and get reduced to gibberish.

Is that even necessary? We tolerate it now, but there was a Free For All period in the past. I wonder if the market would solve spectrum allocation better - OR in areas where every frequency sounds like an annoying CB radio channel, people would do something more productive like read a book. The case is stronger for emergency spectrum reservations and ATC. That can also be done at the state level with interstate agreements. Feds don't need to be involved.
