Remember that the FDIC is not funded by the government - it is funded by premiums that banks pay to get their "insurance". In this model SafeBank would have to pay a premium to the FDIC to get that insurance and as many small banks have found recently (when the premiums went up) those premiums are not insignificant. That's not to say that the government would not bail out the FDIC but to date there has been no reason to do so as they are completely funded by their clients...
