There are very good arguments against net neutrality, for example Netflix paying to have a server filled with 4k content nearer their customers, but the dangers of providers restricting some content is massive.
Imagine if the ISP, at the behest of a TLA agency, decided to massively slow down all content it couldn't decipher, well there goes your VPN. They could ask for the key to speed it up but there goes the whole point of having a VPN.
The best solution is for the ISP to have to* provide unfettered access at the speed you pay for and if content providers want to pay them extra to give YOU better service then good on them.
* This will require some form of regulation, not necessarily as restrictive as title 2.
