It's an analagous moral hazard, though. Even if bringing a bank down threatens the banking system, it must be done otherwise banks act with impunity. It's little different with bankers and "stupid and illogical law" - if we rely on discretion for which laws we apply, then we're entirely corrupt. We must apply the laws we have and live with the consequences, otherwise we don't live in a lawful society.
I see this as an absolute. I don't really see how it can be otherwise.
