I don't know that 'Net-neutrality were, in fact, a good thing; but, even on the assumption that it were, state action is not the proper way to promote it.
'Net-neutrality can be promoted by how people do business with ISPs. At one end, subscribers can consistently migrate towards those ISPs who deviate least from neutrality. At the other end, website owners can impede access by ISPs that do not practice an acceptable degree of neutrality.
In fact, Google and Facebook could effectively impose neutrality by announcing that, in one year, they would begin blocking access by providers who did not make pledges, renewed annually but each extending for ten years, to practice 'Net-neutrality. It might, however, require state inaction for these heavy-hitters to make such a demand. Specifically, Congress might need to clear a path in anti-trust law to allow such a policy.
