Sorry rune, but we can't use gold as money.
Its been proven that the only way money works is by using the fiat type of money. One that is considered legal tender but has no value.
Actually, history has shown that sound commodity money is the way to go. For example, the Byzantine Empire was the most prosperous nation in the world at the time because their currency was sound and trusted. Fiat money loses value far too easily and at some point, people lose confidence in it.
