If owning a home becomes the new anomaly and living/working on roam is the new norm, would fixed housing eventually be devalued for the main population?
You can't get much cheaper than this. When people talk about the rise in housing prices, it's invariably speaking of not only the most populated, but also the most economically prosperous and desirable areas in the country. And in these places - no, housing and land prices will likely only continue to increase as demand is unlikely to waver anytime in the foreseeable future, yet supply is strictly limited - even when expanded.
