You're thinking of Bitcoin as the modern equivalent of "the free and unlimited coinage of silver". (Read up on the Free Silver movement.) That was a different problem, though. That period had a growing economy with a fixed money supply tied to gold. The result was severe deflation. That's not the problem in the current US economy.
Right. Now we have a stagnant economy (limited by oil resources) and a wildly out of control money supply managed by criminals in designer suits.
Oil scarcity is not our biggest economic problem. Not even close. What scarcity there is is exacerbated by poor policy rather than dwindling reserves.
