I can’t follow your logic very well; but the bottom line is, the FDIC will always give you green pieces of paper for the insured amount, one way or other. What those green papers can buy is a different matter entirely.
BTW, when the treasuries reach 18%, your best bet is to move out of US $. Even consider moving to a non $ locale if possible. There will be far worse things (like social unrest) happening besides inflation then.
