There is plenty of demand for living in dense walkable places, which is why they're more expensive per square foot than houses in the burbs. You don't need to recharge your car if you don't have one at all, which is much more sustainable.
Mh, I'm from EU so my view it's not on the current USA population but here while there are some who want to live "at a hyper-short range", that's all but NOT sustainable: they do not pollute, as single humans, but they need a supporting structure who pollute much.
The denser an area is the more territories around are needed to feed it, to a point of 1000+miles ranges vs few if population is not that dense.
Anyway, at least in Europe people who want to be in cities normally are a not so marginal cohort, but still far little in size than the one who want to flee, only few countries where services are not developed outside cities have different mean opinion.
