Ya, I got into debates over this. People would tell me that you can't stop the internet, it's designed to go around "damage" etc. True, but I always countered that laws trump everything and that you should expect law makers to screw it all up. Especially if those law makers are American. And sure enough....
The fact is we can't rely on technology to get around bad laws or authoritarian regimes. It's worked for a bit in places like the middle east, but it's just a matter of time before they decide to force change. Iran is talking about completely cutting itself off from the world wide internet and replacing it with what will effectively be a nation wide LAN. Technology can't help if politicians grab a hold of it and smash it to bits (ok, bad attempt at a pun).
And you're right, the first world isn't much immune from that either, we just have different problems. The telecos actually haven't cared what goes through the pipes so long as they can get their cut from it. Although, now they are turning into content companies as well, so it will likely change and change very quickly - for the worse. So far the FCC/CRTC are the front line and last line of defense for net neutrality, and they've been taking flak from the industry and industry bought politicians, which are many. Most common people are oblivious and will likely side with the content providers. Why? Because it seems people are quick to trade freedom for a little bit of convenience. When I talk to my friends and family about this sort of thing, they sit there and listen and in the end they just tell me, "But I just want it to work, so I buy an iPhone". Frustrating to say the least. The real kicker is that more open iPhone alternatives like Windows Phone and Android are just as easy and in many ways better, but they're hooked on the Apple marketing BS. And using this model the telecos will entice people into their walled gardens of movies and music, where buying access to the internet is now really just buying access to their media store.
Sure, it'll be nice and easy, but I can't think of a worse fate for the internet.
