Why can't you replicate gold? What is gold? It's some elementary particles (like quarks) arranged in a certain way that we all agree are valuable. We could easily agree that some other arrangement is valuable (such as Aluminum).

Here's an interesting presentation by the Winklevoss twins that steps through the elements and narrows down which could be used as currency and why:

good point...also what happens if we start digging on Mars, or some other planet and find 1000 tons of gold?

187,200 tonnes of gold has already been mined. So another 1000 is going to be a blip. At 1M it could become interesting though :)

I am certain that asteroid mining will happen sooner and be far more profitable.
