How does that theory outweigh the theory that government is under the pressure to bow to the will of the people? Particularly when even with healthy competition, the only thing that incentivizes a given bank to do is be slightly better than their nearest competitor in some way—whereas while your specific vote may be one among many to the government, it must follow the will of the people when enough of them agree that something needs to change. I can switch banks until my face turns blue, but if they've all decided that the thing I want isn't worth their money, and are happy to ignore the option to compete by offering it because they've achieved a local maximum of profit-to-effort, it's not going to do me any good.
