Cool observation and analysis, thanks for posting. I did some more work since your question asking if Kardashev Money is solar backed MMT, I guess we could say that it is, but unlike MMT, it isn't optional, something proactive we might decide to do to stimulate business or not, this is something being actually forced by nature, a physical law of nature.
That force is driving inflation, as far as I can tell, and no bank or other "Authority" can stop it, until they give in to issuing the free funds needed.
To be honest I even feel a little sorry for folk in leading positions in authority at the moment, if they can't see what is coming, it will hit them all the harder, though I know they could do a lot of damage in the meantime before they give in.
