But standards evolve or inflate. The "Treasury-quality printer" might well be struggling to make a copy that would pass a cursory examination by the crappiest commercially available thumbnail tricorder. And for truly "real" stuff, you'd need a replication system the size of a building, at which point it would be cheaper to buy a small starship and rob a bank with it.
After all, we do know that replicators seldom bother to make truly exact copies: our heroes always find reasons to complain about the quality of the food or are able to get forensic evidence of forgery etc.
The "GPL can't be replicated" idea is an inconsistent one when we see and hear that basically everything can
be replicated. But we also see and hear that many things are
not replicated despite this being perfectly possible, which is quite consistent with the existence of GPL-style currency.
