Well maybe someone will invent a new infrastructure, Elon Musk was already looking into global satellite internet, and there really isn't much incentive for new companies to come and lay down line the way things are. If a competitor needs to provide high speed internet to every website available, NN creates a much higher bar to entry. New lines could create some great high speed opportunities as well, the internet lines in the US are terribly old, and if you create a system that completely gets rid of newcomers ability to enter you'll have to sit around for decades praying the existing ISPs upgrade the service out of the goodness of their hearts.
Not to mention there are plenty of people who don't stream Netflix in HD between the hours of 5-9 pm that would be perfectly willing to pay less and get throttled at those times.
