I've tried to respond to RAND technical misinformation in the past also, it's crazy on every count that they disable responses, arguably even crazier the platform let's them. Does the unpriveliged user even get that capability? I am not sure, not that I'd want it, but I did check it out from curiosity. I couldn't see how they did it. if it's not me being backward about using Medium, banning all responses up front looks like special privileged capability to me.
Anyhow on your own analysis of inflation, I would suggest energy considerations now need to be explicitly taken account of in economy, to get any reliability of info. It's not something that always needed to be done, before the advent of solar technology, it didn't seem to matter much that money is abstracted energy, because the base of physical capital in the human economy was something that could never be increased by nature (rather than by monetised human labor), we might say the human economy was always a little autistic, it simply ignores other life exists, ie nature, which absolutely has much greater power than us, to move physical goalposts.
Anyhow the effect of relentlessly increasing use of solar energy is the constant creation of ever increasing amounts of valuable economic product by solar. Since it comes for free per kWhr, which defies conventional economics, the latter tries to assert anything received for free can't be valuable, when of course it's valuable, and actually when we stop using energy extracted from the planet, as we are actually required now to do now, by nature, for any survival at all, we are going to have to accept it's the only thing valuable, the entire human economy has to move to it, to retain any value itself, and while it doesn't, that has to knock onto the value in money.
In the end it's the energy which is important rather than the money, and if money is becoming increasingly less capable of transmitting the energy to us from the new source of energy coming to replace the old, by representing that new energy, then it is money that has to devalue, not the energy. It's the energy we metabolise that has to matter most to us, when push comes to shove.
I would say this has to be the dominant feature now in inflation. If it isn't yet, it will be, coming to all of us soon, this is going to be the main show.
