It's not a good idea to nationalize our network infrastructure. Not now. Not ever. Let me explain: first, it is their network and therefore their property... that is unless the government is giving them our tax money. What needs to stop is the government needs to stop handing out tax revenues to massive corporations.
Second, P2P is the pike which private companies will try to bring in network monitoring; you don't think the government will do the exact same thing? They just passed a broad wiretapping law in Sweden; they promise not to monitor domestic activity, but in fact they don't have to. Gee, I wonder if the Swedes are going to get spied on? And America? I dream for the land of the free and home of the brave, but a lot of times I get land of the monitored and home of the arrested. England? I'm sure all those cameras are to respect the privacy of citizens and only catch criminals.
Third, you don't think the government has its own agenda? You don't think they'll develop their own vested interests, in the name of national security or whatever the latest nonsense happens to be? Why did we go into Iraq...? Or you know... maybe they'd just throttle bandwidth with whoever decides not to shake hands behind the door. I know politicians commit crimes that are never brought to light now, so do I really want those people to have control over the Internet?!
The solution is to have a balance between the two, increase private competition, and push for enforcement of laws that come companies are violating nowadays. Nationalization/socialization will just perpetuate the problems. And that's my 2c.
