All that said, I find it extraordinarily difficult to imagine much if any good coming out of proactive government policy; as SamAtt notes, we don't even have to resort to theory to find examples of AngloSaxon (i.e. the most like ours) governments abusing this sort of power.
OpieCunningham's analysis ignores the inconvenient fact that a company or cabal of them can do only so much to me; the government(s) over me can imprison or kill me. And it's largely through government power that they've limited my choices (e.g. if I were to compete with them by setting up a WISP, to whom do have to get spectrum from? That said, they do generally present a nasty problem as the only source of back haul.)
I'd actually agree with the Tea Party on this if not for two things.
1. I don't truly feel people have a lot of broadband options available to them. Most Americans are still stuck between their phone company and their cable company and that's not enough free market protection.
2. At least in the case of the phone company they have a monopoly on their lines BECAUSE of the Government's half hearted break up of AT&T. Meaning Net Neutrality laws would be the Government undoing their meddling in many ways.
People who fall into that region of the Nolan Chart tend towards the conviction that the markets are private concerns, and that regulation is a cure worse than any conceivable disease.
I should add that while I'm a "big government leftist" on those charts, even I have reservations about net neutrality as a government policy issue. It looks like a slippery slope to me.
