If the government blocks fair competition in a market [through controlling who can provide last mile connections by right of way], they need to provide regulation to enforce fairness on the other end [those that provide last mile connections can't pick and choose whose packets they carry and at what QoS].

There used to be counterweights involved [e.g. Comcast had to play ball fairly] which effectively forced neutrality. Netflix, for instance, wasn't a 'problem' back in 2007 for the ISPs. We didn't have the ISPs pulling QoS BS like this in the 90s because people could and would switch providers. They can't now unless they want to go back to using dialup.
