Consider the scale of the money supply as managed by a central bank using fiat money. Consider the fraction that's not already electronic, paper currency. Do you really think that turning that to electrons will make a difference? For reference, in the US, http://www.federalreserve.gov/releases/h6/current/default.htm http://www.federalreserve.gov/releases/h6/current/default.ht... (That's ~$1028 billion in currency, of ~$9755 billion in M2, to say nothing of other assets.) And when you get down to it, all that makes assets like "gold" (and other commodities) valuable as currency is the promise of being able to exchange it for something in the future. (Unless you were planning to do something useful with the commodity itself, which seems mostly unlikely.) Whether this promise is actually more credible than your favorite fiat currency is a discussable matter, but not perfectly clear.
