You're describing a commodity. However, the commodity isn't the tokens, but the compute capacity, i.e., serving a model. And compute capacity isn't a currency — at least not, until you can acquire compute capacity from one party and exchange it with another party.
dgellow is absolutely right: tokens aren't a currency, nor can you trade them, nor are they fungible. The original claim that "tokens are just a type of currency" [1] makes no sense.
