Oil (like all non-renewable resources) stands no chance as a future source of energy.
Oil consumption is (nessesarily) going down, it will never be cheap again.
What will be left of the market will not be enough to give OPEC a serious means of power.
OPEC is a stupid goal for bitcoin...
Heh. You do know that cars don't operate by tipping gasoline into a black hole, right? All of the atoms are still here, so we can create as much gasoline and other hydrocarbon products as we want, at will. However, right now, it is cheaper to pump it out of the ground than it is to sieve carbon and hydrogen out of the atmosphere and crack up so they can form long chains.
Oil is totally 100% renewable. It is only "cheap oil" that is non-renewable.
At any rate, the "unit of account for oil sales gives dollars value" theory repeated by the OP is nonsense, and has been nonsense for decades now. No one is holding dollars against their will for oil purchases or oil sales, at least not for more than a couple hundred milliseconds. Google FOREX.
