I think the above properties define a currency.

Currencies are tangible, generally recognizable and agreed-upon value containers to be traded for goods and services.

Calling it anything else at this point, I'd contend, would likely be essentially incorrect of its own merits, and I do think trying to separate it out would create confusion as it really does no good at all.

It is certainly a special kind of currency, but no different than some of the other universal currencies that we've had in the past, really, at all.
