I guess the idea of scarcity eludes these idiots???
So long as there was only a small supply, no practical use could be made of aluminum. Once it became an affordable commodity, countless uses for it were discovered and whole industries grew as a result. Aviation and space are two examples. Aluminum created far more wealth once it became a common materiel than it ever did when it was scarce. Gold has so many unique qualities, that I would expect the same thing to happen if it became more affordable.
