I never said Fiat was an asset. You keep pretending like I'm some kind of Fiat advocate and I'm not. I just believe in real assets not make-believe ones, backed by nothing but faith.
Perhaps a good definition of the difference between currencies and assets is that currencies are backed by faith, and assets are backed by physical reality. (However that's a "necessary but not sufficient" definition, so it's only part of the definition, not the complete definition of course)
