I feel like energy may become the ultimate form of money. Likely always will be in greater demand than supply (at least on a macro basis). Probably won't have many "magnitude of order" technological improvements after we crack fusion. And oil and bitcoin are already a form of it, in a sense.

If demand is always greater than supply it means that the market isn't working as it should. In a well-functioning market price will adjust so that the supply is equal to the quantity demanded.
That's fair, thanks for pointing it out. I meant more in general that over the long term humans will always find ways to utilize all the additional / cheaper energy that ever becomes available. Historically the pattern has been:
New supply --> cheaper prices --> new applications --> more demand
I don't think there will ever be such a thing as "enough", even when civilization gets to the stage where we measure in units of stars.
