Internet infrastructure, closeness to grocery stores, homes being up to date, walk-ability, close schools, access to transit, are all improved by building more dense housing.

We can also be quite certain that providing the bare minimum housing pulls in demand from those more luxurious options (wants) to the more economically practical option (needs), because the bare minimum option was never available. We'd be giving people more choices and at least some would take it.

Then if you have so many people that "demand" a certain standard of luxury housing, then they will have to compete and pay the premiums for the actual limited resources like lakefront property or great schools (living near other like-minded wealthier people). That's the realities of scarce resources, and is fine, since there's not much we can improve there. But the major gap is providing the bare minimum of housing which we are currently not doing.
