That's not surprising. Distributing the cars to the customers from that centralized assembly line is easy.
Houses, not so much. Mobile homes can be built and distributed that way, but that's the hard size limit since you have to transport them via roads.
With mass-produced houses they do put together cookie-cutter sections of walls and roof structures at the assembly line and truck those in to the site where they get assembled together. But you'll always face a hard size limit since no section can be larger than what can be trucked in. Even a tiny house is far larger than what a wide-load truck can take on the road.
