Well, ignoring that the whole idea just makes me suspect you live in a fantasy world, ISPs frequently have regional monopolies. They aren't going out of business because thye provide shitty service because the internet has become something people rely on. Losing it would be a big blow.
Comcast thrives despite being absolutely despised by a large percentage of their customer base.
I personally really enjoy Netflix. If they were launching today, they would have to pay off a lot of ISPs so that their videos aren't throttled into skipping and stuttering. Let's say that they get enough venture capital to cover these costs, and they pay the ISPs. If this happens then the ISPs are double-dipping -- they're getting paid by the users to access netflix, and then they are getting paid by netflix to access the users. Does that seem fair to you?
That is literally why every regulation gets passed. Because someone thinks someone will benefit.
Without net neutrality you would have to ask permission from the cable companies, who see you as a threat to their own cable television offerings. They'll either refuse to work with you, or cut you a terrible deal.
I'm not saying that others benefit from net neutrality -- I'm saying that you do as a customer, and you do as a business owner.
Is it no wonder why those don't exist anymore?
Then they can get lower speed internet and/or lower caps to lower their rates.
