Dodd-Frank had really set out to prevent Wall Street from perjuring itself and ensuring that all assets held are legitimate and have some intrinsic value, but those restrictions were cut down pretty harshly around 2017 or so, and the criminal syndicate known as Wall Street (I know, redundant) really exploded after that. It'll come tumbling down again when people try to liquidate some amount of asset and are told it's just "value on paper".
