> You could theoretically have a functioning one as long as you build way more than people need, housing then becomes elastic despite the land below being non elastic but the math quickly breaks down.
I doubt this would ever work out, as a high availability elsewhere won't help here. People pick a place to large parts due to job availability, social factors (close to friends/family), infrastructure (shops, restaurants, sports, schools, cultural activity) which is hard to replicate to some scale.
On a very narrow scale there can be an effect, say in Tokyo, where JR builds some railway station and develops that into a new urban center with lots of local infrastructure and connection to job, school, friends, but that is still benefiting to proximity to the other.
