Physical limits don't matter much when economic limits (transistor cost) are reached much earlier. What matters is not transistors per chip area (Moore's law) but FLOP/s per chip cost. Also FLOP per chip power draw.

Economic limits are imaginary, secondhand effects of the ideological goggles one's society decides to wear at a certain time for arbitrary reasons. USA during the Manhattan Project knew of no economic limits, i.e. they could arbitrarily push them according to the greater goal; China today, for instance, knows no economic limits. But yes, today, in the "Western" world a speech such as "we choose to get 160 zetaflops (10^21) [1] under your desk in 10 years because it is hard" [2] would be unimaginable, also because you can count on the fingers of an amputated arm how many politicians know what a FLOP is.

There is no use in making chips that are not cost effective.

There is no use in synthesizing (C6H6O·CH2O)n [1] (or LK-99, to be actual, real or not) that is not cost effective.

It's precisely this penny pusher rhetoric which in the end will make China win, deservedly so.

"Penny pusher rhetoric" is an interesting name for capitalism. Because, for better or worse, that is what's being described. You're not wrong though.

Interestingly enough, penny pushing also destroys capitalism, see The Man Who Broke Capitalism: How Jack Welch Gutted the Heartland and Crushed the Soul of Corporate America―and How to Undo His Legacy [1].
