do not back fiat with metal
see asteroid mining
next fiat based on "consensus" of said nation-states that print currency
implant what you want in your hand your conspiratorial retard.
the amount of metal in one asteroid that was captured and harvested would be… well worth the haul.
do what then? press gold into forms of currency? such small amounts.
fiat is not a rip-off if the reserve doesn't tax 1%+
coins are good though. unless you switch to 25cent bills and 5cent bills… but that is odd too..could make them half as long though so they don't get so easily confused.
