The state regulation of banks to make them “safer” by guaranteeing deposits has in fact done the opposite. It changed banking from a business that had to be run conservatively, to a business that can’t be run conservatively.

A bank used to be a building that would hold deposits ready for your use for a fee (demand accounts), or it was a way to invest extra money and earn interest on it by locking it up for a term (time accounts).

Now banks are fronts for heavily leverage trading firms to juice returns as far as humanly possible. The better they lever up, the better their returns. There’s no downside because the moral hazard of overt, state intrusion to keeping banks solvent is so baked into the cake that the cake itself is not even cake anymore. It’s all hazard. The bailouts aren’t even tacit. They’re explicit and there’s no real limit.
A thing that threatens to destroy the economy if you don’t bail them out whenever they inevitably go bust is not a bank, it’s a robber.
