That's the point, they shouldn't be "reasonable" nor "appropriate" for an entity as large and with as many resources as JPM. Surely with the 300k employees they have and the literal infinite well of money they have, there's a few competent individuals working there to prevent these sort of "mistakes" from happening, and if not then they should either find some competent people, or cease to exist.
What's reasonable about charging them 4 million? It's not even a drop in the bucket, it's a singular molecule of water getting inserted into the bucket if we're talking about JPM.
