Its odd to talk about net neutrality as something that might "perish" as if it ever existed for more than the couple of years before the FCC's order was struck down.
The FCC Order was motivated by a desire to preserve what was seen by many as the status quo ante that was, at the time the order was adopted, perceived to be under threat as big providers began discriminating against certain remote endpoints and applications. Mandated neutrality may only have existed for a short time, but the mandate wasn't the origin of neutrality it was an effort to preserve/restore what was perceived as pre-existing neutrality
