Making houses 3 orders of magnitude smaller and cheaper isn't very popular.
But I get your sentiment.
I’d love to see some disruption of those markets. Let’s see … laws that promote rather than restrict development … search programs that reduce friction identifying maximum buildable area lots for sale … trading platforms for combining lots into larger developments … optimization of actual building technology … innovation in ownership and governance models…. Of course, none of those are strictly dependent on MHz.
The problem isn't the houses themselves, it's the land to put them on. Technology doesn't help much with that.
