Earlier quoted context omitted.
Sorry, I should have consistently specified "urban" land. Urban land is not finite (cities grow) and is very high value-added. American policy makers have chosen policies (eg zoning law) that make it easy to produce valuable urban residences. Now they have a massive competitive advantage in high-end residences, so of course they will become exporters.
> Urban land is not finite (cities grow) “Capable of growth” and “not finite” are not the same thing.
> there is a fundamental difference between finite, rent-generating resources like land, and value-added goods
