A currency doesn't necessarily have to be backed by some kind of valuta as long as the tokens themselves are a) in a limited supply and b) difficult if not impossible to counterfeit. The "Steel Credit" would be a good idea if there were some means of assuring each was genuine as needed, preferablly without some kind of callback to the issuer.
