That depends on how long FCC is able to keep it implemented for, IMO.

Something that gets lost a lot in policy discussion is that once you implement a business regulatory policy like this, you create a constituency for that policy. It's an advantage in preserving hard fought gains but that also means the timelines need to work for it. The problem net neutrality faced the first time is that it was (a) late in Obama's presidency, (b) held up by court cases, and (c) reversed early on by Trump's FCC. There wasn't much time for the internet business community to build a business model around it.

If net neutrality is regulated into existence for 5+ years, at that point businesses will have come to rely on its existence. Taking it away will be harder, especially for a big pro-business party if it's getting an earful from megacorporations that want things to stay as they are.

Of course, I do agree that legislating it is the most robust option and would be the best course of action. I just don't see legislation as the only option with any longevity. FCC rules can be that if the timelines work.
