Yes I know, which is why I used that phrasing. As the production of real things made of atoms can't be ramped up arbitrarily quickly.

For example, every doubling of oil production after WW1 took more than a decade to accomplish. And oil men were pretty well known for risk taking boldness.

The physical impossibility of real resource inputs to human civilization doubling on an even faster timeline is so obvious that I skipped pointing it out, and got straight to the point.

That it's incredibly unlikely for even money to double quickly enough.
