The problem's that compliance is so burdensome and expensive that firms don't want to enter the public markets until they're already large (or if they're forced to when their cap tables get too big).
So this regulation that's supposed to help protect retail investors ended up hurting them by putting growth opportunities out of their reach. If you keep the regulations in place, it makes it easier for the rich to get richer and the poor to stay poor, deepening the class divide. But if you roll back the regulations, maybe the crooks will immediately see that as another opportunity to line their pockets by creative accounting, and in another few years we'll see a bunch of big companies go bust, as the lies can't last forever if the money simply isn't there.
Damned if you do, damned if you don't.
