As the US supreme court noted early in its history, the power to tax is the power to destroy. You will surely forgive me if I am a little skeptical of the government having the power to destroy radio, television, and other communications; note that it's actually been done before.
Meh. The government also has the power to drop nuclear bombs and has done it twice before. Shockingly, we're all still alive and procrastinating on the Internet.
The the typical libertarian appeal to fear of tyranny IMO sheds more heat than light.
