I think you are looking at this wrong, some people think that the only way to get things the way they want is to have the government make a law. Others know from experience that freedom from regulation will allow us to get what we want without laws.
Those that want new government laws have no faith, they want a dictator, someone that can make everyone behave. They believe that people in power can do the right thing, when history shows they won't.
Carriers will only throttle the internet if there is a monopoly (usually by government regulation). If carriers A and B are competing, then either A or B will be the winner. The loser will do whatever they can to get ahead and if that means not throttling, then they will not do it, unless the government regulations prevent it. Which they will. Who funds elections, big business.
Remember the statement "you will still be able to use your existing doctor". The government knew that was lie when it was said. Same thing here. Just give them the power and it will be ok. But history proves that is a lie.
Now are you a 2 year old demanding to get what you want, or an adult that understands the game at play?
Actually, I think you may be looking at it wrong. You see, as someone not devoid of logical thought based on reality, the internet hobby known as libertarianism never really appealed to me as a viable philosophy. While I'd love to believe it were possible, it's fairly certain that humans, and most decidedly Americans, are incapable of true freedom. I'll explain that in a bit.
It's odd that you think that the government not allowing a company to do something isn't necessary since they wouldn't do it on their on anyway, even though that is exactly what they seem to be lobbying for, and exactly what happened before regulation. Yes, competition is great and needed, but some regulation is also needed.
Can you explain how a locality with 10 different cable providers would work, if one of them didn't own the actual cable network? Would you actually want to see 10 different providers' lines strung up all over town? What about water? Natural gas? It's highly unlikely that you'll ever see a non-monopoly on these things, without making it a public service. Even in places without a "government approved" monopoly on a utility, a natural monopoly often occurs on its own, simply because it's just too expensive to build dual competing systems. And then, we end up with things like this.
Now, back to my point about humans being incapable of true freedom. Do you honestly think that if we got rid of noise regulations, zoning laws, pet laws, parking laws, property code laws, and all that, that everyone would just get along and it would all be hunky dory? Do you really think that if we got rid of worker-protection laws and safety laws that businesses would just do the right thing? If so, you live in la-la land.
Or, do you subscribe to the "I should be able to do whatever I want to do on my property" mantra. While this is a solid idea in the vacuum of libertarianism, it's not viable out here in the real world. If you want to let your grass grow 4' high and surround your 3 rusted out project cars on blocks in your front yard, while your deadbeat son's punk band practices in the driveway, and your four dogs howl until 3am, that might be perfectly okay with you. But if you think that your neighbor who is fed up with it is just "being a 2-year-old demanding to get what he wants" , then I doubt there's much we can really discuss.
Comcast as a cable company is well known for their deceptive practices and abhorrent customer service, and I've experienced it first-hand. And there is competition in our area, albeit minor. With Google Fiber coming in soon, I'll be interested to see what Comcast has to do.
But the main point being, this free world you imagine, where everyone gets along and companies do the right thing, and everyone is just peachy, is complete fantasy.
