What if I bring my pet elephant to the pasta bar? He's a big fan of lasagna. He can down the entire bar in one trip. Mind the back end, it can get a little messy.
Your analogy would work if certain people were consuming 100 times the average person in pasta, but I doubt any restaurant is going to allow such a customer to stay. The problems many of these ISPs face is complex. They don't have the right people, technical culture, or budget. They simply do what they can with a typical mass-consumer grade service, aging infrastructure, and low budgets. What we want is someone to sell us a carrier grade connection to our homes. That'd be great, but at a few thousand dollars a month it is probably out of most peoples' reach.
Subsidizing the network with municipal investments seems like the right route. Around here though the 'good ole boys' lock up those lines nice and tight. They don't want anyone fiddling around with 'new services.' That's politics, and you might get somewhere by going the political route. In other words - what are you doing today to ensure that tomorrow you're one of those 'good ole boys?' Hardly any of my geek friends get this. They think there will be some kind of magical social awakening some day. It is almost like a religion. If we want to change, we have to get educated. I'm too lazy to care though, so let me know when you get on that. I need to go hide in my cave from the Swine Flu pandemic.
