<cyncism/>Currency is just copied now, but it is by the same issuer,
in the form of additional currency being printed by the Federal
Reserve.  One could make the argument that the fed controls how much
currency is printed, but since the fed stopped reporting how much US
currencncy is printed(
in 2006, there doesn't seem to be a check & balance in place.
