aclatuts cannot build enough units, but the country of the USA can, because it has a finite number of people in it, and immigration controls.

If you would like to be proven conclusively wrong, I'd suggest looking at Japan. Its zoning stayed much more liberal than the United States and despite the massive size and growth of Tokyo, it stays affordable. Even in SF, some of the largest housing advocates are the tech companies that don't like having to pay employees enough to live in SF[1].
