assumed "all mined state" and a "really growing economy" (for instance doubled population adding to economic cycle, not the "0.x" yearly growth postulated in gov statistics without calculating inflationary effects) there is an automatic deflation IMO. Which fuels speculation, creating bubbles... Ingenious yes, but no magic bullet stopping bubble effects.
