The problem is that people want "cheap" houses, cheap houses coupled with modern regulations = sealed boxes. The average joe doesn't give a shit about building quality, it's all about getting something big and as cheap as possible.

This costs power and materials. Old houses dont require that. On a global scale, that increases power and manufacturing on a huge scale. Why are we throwing power and more modern materials at a problem that was solved in Roman times?
This would also reduce cost, helping the 'cheap' houses issue.
