Without meaning to be rude, you do not seem to distinguish between a statement and an argument.
You state: 'global demand will always exceed production, and so there will be no demand destruction'
If so, why?
What would be the effect of, for instance, a run on the US currency so that it became effectively worthless - would this not reduce demand?
You also do not distinguish terms tightly enough even in your blanket statements: demand technically always matched supply, it does not exceed it or fall short of it.
The question is: at what price do they balance?
If the price were lower than today following major recession then the statement you make would not be true.

U.S. demand can virtually collapse, and depletion will remain much the same. The U.S. is 1/4th the demand. As supply decreases, demand is progressively higher by comparison.
