Pardon? I believe that's a little revisionist, as you stated, and what I was specifically referring to is "Currency refers to physical money."
You then list all the ways in which other forms of currency aren't currency, which is the point I disagree with. While I agree that a credit card isn't necessarily mapped to a tangible dollar figure, and that yes, it does refer to a line of credit, I disagree that it isn't considered currency on those grounds. Does a debit card more appropriately fit your definition, or is it disqualified because the actual dollars are elsewhere?
Regardless, I think all the relevant points have been made, and further quibbling on the point isn't likely to benefit anybody in particular, so I'll bow out.
You don't exchange your debit card during the transaction.
It's perfectly legal to map USD > token and exhange that token. It's legal to create a token that you will map back to cash. It's not ok to accept other peoples tokens that does not represent actual money that exists.
Travelers checks are an example of the first kind of token.
Poker chips are an example of the second kind of token.
You can accept a Travelers check from someone else. But you can't operate a business that accepts Poker chip's from someone else.
