Gold has not always been the Ultimate Currency. Gold has always been a Commodity that was always affected by supply and demand like all commodities. FIAT, on the other hand, doesn't devalue by the very fact of printing more of it, it can actually have quite a stable "value" as the Steem whitepaper points out. To boast that the market is small only shots up red flags for the obvious pump and dump that they are gearing up in this "change" from fiat to gold.

Many people still believe that we had a "gold" standard and that you could redeem your dollars for gold, but that has NEVER been true, ever since the first gold back dollar issued by the 3rd Congress. The reason why we went to war for Independence was because we were forced from "fiat" money, called colonial script that was issued by each one of the colonies, under the genius of Franklin, into the poverty-ridden pre-revolution times which were a direct consequences of not enough Gold coins to pay for labor and goods. The issues are stability, and you cannot have stability from a Minable Resource that could devalue the entire supply by any chance discovery of a substantial supply which is what marked numerous gold rushes all over the world and which devalued the commodity in turn.
