I disagree. This lawsuit was against a single individual. There is nothing here that is threatening to crypto as a whole.
One thing that will make it harder to regulate as time goes on is that more people will be financially involved. From traditional finance getting involved through funds, to the masses getting involved, the ecosystem has grown far beyond the fringe, and will continue to do so with each successive hype cycle. Hell, many governments themselves have skin in the game now.
I’m curious how you think serious crippling legislation or enforcement would play out.
EDIT: additional thought… this case protects the industry, not the other way around. The industry was being attacked by a fraudulent individual, and the government defended the industry.
