If banks can't fail there is no freedom

To be free requires that banks can fail. If banks can't fail then they will be able to increase the money supply which means they can extract wealth from the economy. If banks can't fail then fiat money has value (otherwise the government would not be able to save the banks) and so banks can then effectively print money. If banks can print money (for profit) the rest of the economy is not free and there is no freedom. There is no freedom if there is bank deposit insurance.
