Not the same thing. Banks are insured against robbery and theft, so if something like that happens, customers don't lose their money. In addition, there's an insane amount of fraud protection in the banking industry, and billions of dollars of vested interests to make sure criminals are caught and prosecuted.
Good point. Even in the worst case scenario, banks can fail and get bailed out by the public. But once information leaks, there's no "bail out" remedy possible... you can't really put the "information" genie back in the bottle.
Can you say the same about cloud services?
