Within the Bitcoin community, there is a strong need for a term that means "normal money, the kind that gets printed by governments, as opposed to gold, Bitcoins, stock certificates, commodities, and other fungible stores of value". The community has been using the term "fiat currency" for that. It is, effectively, a new meaning of the word (although VERY closely tied to the older meaning). Unless you have a better term (and can persuade others to use it) you may need to accept this new meaning for "fiat currency" in order to effectively communicate with others.
