IMHO, this isn't the same as residential electricity because you either have it or you don't. Okay, sure there are the few residential exceptions that might need three-phase or something like that. The watts used for one device will work just fine for another device. Most houses have a 200 amp service and that's all most people are ever going to need. That 200-amp service has been the same 200-amp service for 50 years. And if I use 10,000 watts all day, that doesn't mean my neighbors won't be able to run their fridge.
My point is that eventually, a few people will want to get full-blown 4k video through their connection to multiple TVs in their house and that's going to take major infrastructure upgrades. Most people aren't going to need all that so do you think they'd be willing to subsidize a few high-bandwidth users? Do you expect the ISPs to just eat the cost of keeping up with bandwidth demand? One thing is for sure, government regulation rarely precisely targets the entity in private sector it's intended to. Take a look at your utility bills and see how many regulatory fees are being passed on to you even when you don't use the service.
