John the key point of the Kardashev hinge observation is that Bitcoin is forcing up solar adoption.
So every token has associated with it a capacity of solar energy capacity.
In theory that can equate to something assigned, where there is need, once assigned, no more transactions (or work) is needed. The network could be static, with the density of distribution at various points defined by the current state of the Bitcoin ledger, where continuous tokens of another kind, or dollars, supplied by that energy are generated endlessly by the power assigned. To increase wealth at any point, for exanple to fund a high consumption project like space research or whatever, only a small number of Bitcoin transactions are needed, to reconfigure supply, to get more token flow as needed at that point. Besides that it would stay static, so no wasted work.
It Engineers similarly to a piped water irrigation system with value at any point computed by market value x token flow, like pressure x flowrate at any point in the system.
We would regulate that by everyone wishing to take part in the markets which would be non-profit, (in absence of scarcity that might be leveraged for profit).
There we would assign funds to the things we value in the world, like we saw happening briefly on the first issue of massive stimulus, equivalent to 10,000 dollars per person in one month, oil prices went negative, and some “bankrupt” company stocks soared, whilst the dollar value itself went up.
All it needs to start it, is for the banks to reassign debt, as explained earlier, then everything else falls into place, funded by solar powered free money.
I hope that helps explain.
