This is partially at least an emotional problem which you cannot only tackle with logic. The other problem that you’ll currently see is that even if you can convince people that tearing down their house and building a new one in the same spot, they’ll often still want to be able to afford one of the new flats - and that’s currently not a given. So people understandably prefer to stick what they have.

So a fundamental ability to compete is IMHO a basic requirement for building more chairs.
