I’m curious, what recourse do you or anyone else have against the CIA, FBI, or any other Department of Justice or Intelligence agency that you wouldn’t also have with a commercial bank?
To your concern that these three-letter spooks will spy on you: what would they do that they're not already doing? That isn't to excuse the spying; I'm just pointing out that these are separate issues. Tackle the fact that the NSA compiles all unencrypted HTTP traffic separately from the fact that JP Morgan Chase knows my financial history and doesn't have to care about keeping it private per my idea of private.
(Unless you're asking whether the protections are useless against corporations. Then yes, they're useless.)
