I agree that having a banking system in any major degree at the whims of politicians could and likely is a bad idea.
I don’t think however having the Civil Service running a public bank would be a bad thing though. Career government employees are at the whims of politicians no more than private businesses are, has been my observation, and can when structurally enabled make good sound decisions.
I think having a public option for banking in this light would be positive
Except if you look at mortgages as an example, the government already has a huge impact on who gets loans (via Fannie Mae and Freddie Mac, plus programs like USDA home loans). That influence is largely to expand access to people who would otherwise get cut out of the system.
Deposits in a bank never go anywhere. All that happens as you “move” money around is the ownership tag changes. And that tends to change the price the bank has to pay on those deposits.

Yes that's why I said there's some value in having private credit creation. In fact, my comment was just lifted from this lecture by Randall Wray where he says precisely what you just said:
You do not want the government, which is supervised by politicians, picking who gets loans.
