A few concerns of mine:
1) ERoEI (energy returned on energy invested). When more energy in one form is expended whereby to yield less energy in either the same or another form things get interesting. For but one example, if it takes more refined gasoline consumption whereby to extract crude oil from the ground than can then be converted into gasoline via processing and refining the extracted crude oil, then does it become game over for using gasoline power to extract crude oil?
2) What I will refer to as RRoEI (resources returned on energy invested). An individual example: Rare earth metals are required for (among other things) solar power and electric vehicles. When the energy expended whereby to mine, process, refine, and market the rare earth minerals exceeds the value that lies within the rare earth metals, does that mean the pursuit of rare earth minerals has hit game over?
3) The potential that we will eventually reach "Peak Everything".
4) High Grading. High grading is the human nature driven tendency/desire to tap/mine/exploit the richest resource discovery zones first, whereby to deplete the very best among them first, making all future resource mining more costly and less fruitful, and also much more energy intensive.
5) When extracting oil from the ground requires fracturing the very earth itself, as opposed to simply sinking a shaft, this seems to indicate that all of the earths simple to reach oil has already been high graded, leaving only the most hard to get at dregs that require such drastic measures.
6) Will throwing ever more amounts of money fabricated out of thin air always solve problems such as the scant few I've listed above?
7) A joking way to look at all of this: A woman is trying to hang a picture by driving a nail into the wall, but hasn't got the right tools. Her dad, who has been watching, quickly sketches a picture of a hammer on a piece of paper and hands it to his daughter. The daughter wails: "Dad, that only works for money!". (note: joke stolen, not original to me)
