What a ridiculous suggestion. Risking the life of a child slave is the only ethical path!

From historical precedent: yes.

All people need to have something hold worth as currency is the knowledge that it can be used somewhere vaguely useful. A nearby interstellar state/society means that anyone who goes off world would use it, which in turn means anyone who lives/deal with a major settlement would be fine with it.

Roman and Imperial Chinese coins ended up being used as currency half a continent away (and were all devalued well below face value or already fiat) at much of their given value throughout (and even after the fall of the Western Roman Empire).

In Skeleton Crew, Old Republic credits are apparently worth a shitton during the New Republic period.

Which makes as much sense as bottle caps as currency in Fallout if it's by fiat.

I think SW credits might contain energy or something with actual utility, that's the only way it would make sense for old credits to be valuable without any government to require taxes be paid in that currency.

But wouldnt that imply crypto of any kind has value?

Pls explain
