Prefab homes have been a thing for decades. And have a lot more options than this thing since the walls don't have to be hinged together for shipping. Unfortunately, zoning laws in a lot of places class them the same as mobile homes, limiting them to being built either in areas zoned as trailer parks or rural unzoned areas, otherwise they'd probably be more popular than the standard stick built homes.
So cheap houses are limited more by regulations, than the technology.
IIRC in US you don't need to register or get approval for the house that is not permanently connected to its foundation. Doesn't that allow to build that prefab houses on any private land? Just build them with detacheable connections to foundation so they accounted not as real houses that fall under all that regulations. I also saw multiple "build house by yourself" videos where that point about connection with foundation was specifically mentioned. People built houses from sea containers or as log house avoiding approvals and other stuff on their land.

Depends a lot on where they're building, zoning laws and building codes vary pretty widely.
So that "unmerged with foundation" thing is state/land dependent?
Yep, and in a lot of states it's also county or city dependent.
