Gold's "intrinsic value" is a fig leaf. For all practical purposes, its only value comes from its scarcity in the same way Bitcoin does, and in that respect, is a pretty good online simulation of the use of precious metals as a store of value.

The only value of anything is what someone is willing to pay for it at a given time. Industrial and decorative uses of gold might place a floor on its value under most circumstances, but that floor is maybe 1% of the current market price.

There's also significant friction involved in using Bitcoin for transactions -- transactions take many minutes to clear, there's no mechanism for chargebacks, and there's no mechanism for recovering lost coins if you lose the key to whatever wallet you're storing them in. It's a bit easier to use Bitcoins to buy a pizza online than it is to try to buy one at your local pizza joint using a bar of gold, but the hassle is a difference in degree, not kind.

There actually are futures markets for Bitcoins, but not ones any sane person would trust with their money.
