This is already happening. Banks report all transactions above a very low threshold under various justifications and laws, plus the government is always going to be the front-of-the-line creditor and can trivially find out your entire net worth at will. We could at least look to cut out rent seekers on the baseline services and make banks compete on performance and value-add. As a customer and shareholder of banks I feel like I'm getting ripped off on both ends.
