Cool article, helping understanding of pricing as market stands, but something still missing from most analyses, including this one, is the effect of Joules received for free, which are further received from off-planet, and put to use, on the economy.
Those Joules convert to fuel (Hydrogen), and food ("Solein" for example), but no money is issued on that valuable solar product, which is added to the existing stocks of commodity capital.
For thousands of years we could consider that commodity base as a constant, and we still do, but now there is a problem, as it is now actually physically scaling up, continuouesly accumulating, whilst the solar energy capacity steadily ramps up.
This also breaks the Austrian Economics principal of money issued balancing with product creation, therefore explains entirely the inflation we are seeing, because as solar energy necessarily scales up, with no money being issued to reflect it, money is increasingly becoming less representative of actual product, the only product kind which is ultimately sustainable, so the most valuable kind of product we know.
Money can't be issued on it as debt, because promises to pay can only translate to work, whereas there is no work associate per Joule with solar, as you point out, this is why it is free, and also why it creates no pollution.
The only way money can represent it is for money to be given out for free.
That kind of upsets the whole applecart of capitalism, by blowing away all value we might have thought existed in capital.
I wonder when those in charge of issuing money will acknowledge this?
I call it "Kardashev Money", in the stories I've written about it, for want of a better term. Maybe someone will come up with a better one, when it starts to become mainstream discussion.
I couldn't care less, only that it does actually go into discussion at some point, prefererably ASAP, as it is the quick way out of all the problems we are seeing.
