Maybe for economists they are different things, but in nature, energy underlies and connects all things, it flows from the sun as radiation, and in trees via nutrients.
Money carries energy, historically always from capital, but since capital is just stored energy, it quickly gets outweighed by a never-ending flow of energy from the sun.
By your own prinicipals of Austrian Economics, it has to reflect actual product, to be valuable. If there is a growing pile of product going unreflected, and there is, from tens of GigaJoules per second of energy being received and put to use by every country, the only way it can be reflected is by money donation to all people, the markets will not accept anything else.
So money will come to transport energy from the sun, each token representing a number of Joules from the sun, whereas it used to represent an amount of gold.
This has been something thought about for a very long time, as far back as Nikola Tesla, he knew that with free energy, there would come free money, hence the reason he was defunded by his only funder, JP Morgan.
But now nature is calling the shots, not JP, nature appears to be at check, with one move to mate, it seems to me.
It will be much better, when we can Engineer the system of money using sound engineering principles, rather than what seem to me to be the principals of economics, which so often seems removed from reality.
What we are about to see, is money becoming integrated with nature, which will fix an awful lot of problems, it seems to me.
