edit: looks like he edited his comment while I was replying; his comment originally ended with, "I hoped your ilk would never find currency on this site, but I guess the day was going to come.", and was that way for at least 30 minutes before I replied.
In the context of economics and law, currency is physical money.
I think you are more interested in winning the argument than being correct.
