^ I think what you mean is that affordable housing is scarce. 'Land' in this regard means very little if you can put together giant orbital habitats, or apartment buildings. Of course, whether people can afford to live in those habitats or apartment buildings is a completely different story.
As for post-scarcity, all that means is that there are sufficient resources to meet the needs of the population and that such resources maybe easily procured and distributed. It has nothing to do with the absolute amount of resources available.
