No, that happens immediately when the crash happens, not down the line.  Without a bail out, the "institutional" banks become insolvent and you get Cyprused with a haircut or bank holidays.  The alternative is to just bail out the banks every single time it happens, but then you get hyperinflation and Bitcoin + metals still win there anyway.  By holding cash in a bank, you're just gambling that the banks will be bailed out in an orderly process, but even if they are bailed out, that doesn't mean the one you have your money in isn't going to disappear or give you a haircut in the process.  There's no point dealing with the counterparty risk when there's alternatives.
