That's something conquerers do every time.
When I was in HI on vacation, I saw some notes that Japan had printed up for the Australians to use as currency, after Japan took it over in WWII.
And the value of the currency generally increases dramatically from its inception for some years. When it starts, there is little confidence in it. It acquires confidence for (among other causes) just being in place for an increasing amount of time. If the administration is reduced to taking credit for time passing, then holy smoke(!!!), let's get rid of them.
