This is not what the crisis is about. The housing crisis is not a lack of space to build nor a lack of materials. It's a lack of housing that's both desirable and affordable. Most people don't want to live in the middle of nowhere with nothing around, even if it costs very little. Look at Italy for example, they're giving houses in rural areas away for free, granted you agree to permanently live there, and they still don't have much in the way of takers.
