What you're describing is how net neutrality works, not how the Internet works.
> First, bandwidth is limited. It's whatever download and upload you sign for.
I said that I don't encourage bandwidth limits, not that it wasn't limited. The point is you usually sign a flat fee, you don't have universal access and then pay for traffic, more like in a country like Andorra.
> Second, there is no such thin as "full speed access to Netflix" or whatever. It's limited by your own bandwidth at least.
It's only limited because the ISP has limited it, it's entirely possible to give someone with a slower overall internet connection a higher speed to certain services.
> They don't have to update their infrastructure every time a new web site comes up. As such, access to Netflix, Youtube, or http://loup-vaillant.fr are not separate services.
I don't see you point. ISP do peer directly with services, but I never said they had to. You just have to have a separate exchange for full speed services.
> ISPs that treat access to particular web sites as separate services are just plain lying. The real "separate service", for which they actually spend money, is the throttling/filtering/censoring infrastructure they have to put in place to charge different web sites differently. Text book malicious features, not unlike DRM.
I don't agree with throttling, but "throttling" (or congestion) does occur naturally on the Internet.
I think you really don't get my point, so I'll try and explain in another way.
Today you pay a higher amount for something like a 100 mbit or 1 gigabit connection. That's for all the infrastructure and bandwidth for giving you that access (or at least hopefull something close to it). How this works differs, but generally your ISP would pay to access bigger networks.
Now imagine instead if your ISP only guaranteed you a certain amount of normal Internet traffic, either as bandwidth or data. And then it would be up to the services to pay for the infrastructure and bandwidth to deliver their content at a higher rate. It would really just be a formalization of what's already happening with transit vs. peering. If you want to see it from a technical perspective, how it is today, imagine having 10 mbit to the open internet and 1 gigabit to all the services that your ISP peers with (even in the extended network). Then imagine possibly your ISP getting paid by those services instead.
I'm not saying that it's a great idea, I'm saying that it is a winning one. Because consumers would pay less, ISPs would require less infrastructure or pay for less bandwidth (as you said these things are related) and it's actually creates incentive for people to roll out Internet access. And if you want net neutrality it's an argument like this you would have to be able to argue against.
