That’s fair and all, I just think “this isn’t Facebook, you can’t just ban me from my own money” is a perfectly reasonable hill to make other people die on. Like I said, it’s not theft if it’s yours and it’s not murder if it’s self-defense. Stopping someone from robbing you is a textbook self-defense scenario and power distance games with a ban button at the backend and a polite teller at the frontend doesn’t diminish that.
Just pull the trigger until the problem goes away or you’re dead. If you meet God with your guns still smoking you’re going to be praised for it.
