Im not sure why you say TV stations dont broadcast anymore. Theres a lot of TV antennas for sale at Walmart. At such time as ALL radio and TV are distributed in ways other than over the air broadcasting, which I agree is coming, then I suppose licenses will no longer be required, anymore than having a website does.
Im for less government. A lot less. Im also in favor of government staying within its legitimate functions. Exactly what those should be are debatable, obviously. Some regulating, whether thats deciding what side of the road to drive on, or setting the drinking age, etc. are probably going to continue.
All television broadcasts are now mandated to be digital. The analog airwaves are free of everything but government usage I do believe.
