Literally everything the government regulates becomes a mess and a boondoggle. Health care, housing, and pensions all the way down to city building codes (I have a friend who needs to replace her windows in San Francisco, and the city government has decreed that they can only use wooden frame windows because of the aesthetics, even though they are more than twice as expensive)
I have been in and out of government, and I have met the people who will implement "net neutrality", and I wouldn't trust them to install my cable modem.
And inevitably, big business had (and will continue to have) their lobbyists in the room, making sure that any regulations benefit them and prevent upstart competitors.
Unintended consequences will prevent new technologies from forming (Look at what the GDPR laws are doing to blockchain...must be able to delete your data, you say? And the ink isn't even DRY!)
"Net Neutrality" is nothing more than an Orwellian named, amorphous and vague idea that nobody really knows what it means.
Give me a shitty natural monopoly that I can compete with every day and twice on Sundays over a government created sclerotic ologopoly.
