If you're going to restrict a bank from using your mortgage to enable loans for endeavors that will hurt you (or selling the debt to somebody who will do this), I think you do need a new kind of accounting.
Accounting predates banks. You do not need to invent some kind of new accounting system to rid yourself of banks.
That said, banks do provide a useful service for many people. However, that service doesn't magically happen. One has to choose the bank they are comfortable employing. Which, again, requires an interview before accepting a bank to work for you. That is where you can make sure the bank you choose to utilize the services of aligns with your "cultural fit".
