The brick wall thing seems like a particularly silly analogy.
There are a lot of question marks between where we are and where we want to be. It seems imprudent to assume that they will all be resolved to our liking.
It's complete economic and historical ignorance to assume the best way to answer any of those questions is with central planning in the form of transaction rationing.1000 times this.
I know rationing from my personal experience living in a part of the USSR. Imagine standing in line for 6 hours with your mother just to get meat for Christmas...
I would advise anybody who does not get what "rationing" means and what it leads to to try that. It should be an enlightening experience.
The less centralization & control, the better. Let the market decide.
Mining should be stopped at all.
