It does look like bullets could become the last money, that is pretty dark scenario :)
But the vast majority don't really want that, I trust including your good self.
Energy is the money of nature.
The task in hand, it seems to me, that maybe all humans have to consciously participate in, more or less, is to make live energy become the thing which is monetised in humanity, rather than as it currently is; stored energy (capital). That would make it conform with the currency of nature, becoming part of the system of nature.
To me it looks like this will happen automatically, when free money is issued.
There will come a point when free money is demanded by people left with nothing, millions of people.
Then governments will give it.
If that money given for free is believed to be only MMT, like it maybe was after it was issued during Covid (When oil prices went negative) then I don't think anything is fixed.
But if it is understood to be actually representative of freely donated Joules of energy from the sun, put to use by us (Therefore being valuable physical product, which added value to Earth), then I think the problem is fixed, because then we have finally aligned money with live energy, rather than stored energy.
