If there's one positive that can be made of this admin, it's the realization that all the things that we thought went without saying ("don't profit from the office", "don't insider trade", "don't casually leak confidential information to our enemies") need much stronger enforcement mechanisms.
They didn't go without saying: there are laws on the books explicitly making them illegal. But a law that is not enforced is not justice, and a law that is unevenly enforced is an injustice.
Too much of our government requires/required its trustees to act in good faith. Clearly that was too vulnerable. And I realize it sounds naive to think that past trustees were acting in good faith, but there are relative degrees of that.
