Sure, but I don't think it should be the government's prerogative to shut down businesses either, just on the grounds that regulators find the industry annoying. If people want to buy their silly crypto trinkets I don't see how moving it behind the curtain of a brokerage actually helps anyone.
I mean, the whole SEC thing is a bit of theater: they can't actually do anything to protect against frauds and scams and bad investments. All they can do is to push assets into the high-speed traffic of professional traders and hope that the market sorts things out for itself.
