The Earth is not a closed system.
I get your point though.
Lets say the Earth is not closed shut in the universe of things, but as closed as your body cells in operation, but for us as humans and our lifestyle and the resources we have to mine to maintain our way of living, for all practical purposes its closed, meaning if we run out of the basic resources, we done and starve to death, ands thats real, we just did not experience in yet on a large scale. Our ability to mine outside of earth and bring it back not wasting moree reasources in the process of getting it, is slim, we as humans are just too minute in the universe.
The real simple way(Deeply abstract, money is just a medium) of how our living is possible as it is, is probably never talked about, so we are all born into it, having it, not fully realising the basics. We just don't see it yet.
Money cannot be wasted, but resources are. No resources, money is wortless, not even a consideration at that point. Money just flow from one account to another, but in the process you can be sure resources had been wasted, meaning it does not regenerate itself automatically, it may appear that way till the bottom fall out.
Basic resources MUST be cheap(Involved in everything upwards you have no coice you must use these just to basicly live today, otherwise it will destroy the smartest monetary systems exponentially over time, no matter how much money you print and dump into it,3rd/th/5th world countries just don't get it.
So those with energetic ditital eteopiaetic plans & pipe dreams and schemes and go balistic about it, make sure you understand this 1st, its going to very difficult to turn back apon in two-to-five generations.Destroying the basic concept of living on a "closed plane" like Earth at 7 Billion plus, is going to be hell to pay.
Remember to old power systems grew gradually over years, and the new systems are dumped on us at 7 Billion, its NOT proven at that scale to work, its going to be a sudden shock state like event, of course a few will get ultra rich quickly, but where are they going to flee too, Mars perhaps-?.
