Aviation relators just allowed boeing to self certificate again. Avition has a lot of historical regulations and can work through sheer inertia for years.

But the whole point is, regulator wont have teeth. They have teeth when politicians back them. And as of now, politicians back billionaires and deregulation. Wall street hates regulators, billionaires hate regulators and sizable part of population prefers people dying if it means they cam hurt libs and ennemies.
