And that's fine I guess? It's important that there are banks that are too huge to go online-only.

It will be easier to comply for other industries. From my initial example, for event tickets, they wouldn't care much whether they scan a screen or a piece of paper when you enter, and they could let already-existing box offices sell the tickets. For government agencies, those already have offices, so nothing changes. For parking, just bring back the kiosks.
