Welding for high stress, corrosive, high vibration, high heat and high safety requirements is extremely difficult and highly skilled labour. And rightly so. Regarding house building, there is only so much that can be pre-produced. Assembly is still on site, and that will always require rework, nobody can affors the site preparation and parts manufacture at the required tolerance levels to avoid that.

  Or modified shipping containers. Those, as well as mobile homes, have significant trade offs so.

    Yes, they are trade-offs. But I'm sure many of them can be overcome, with some research and development. Eg camper vans have also become a lot better over the years. They benefit from not being banned in the US.

I think you are unaware of what has been achieved for years already in Europe by companies like Haus - https://haus.tech/ https://haus.tech/, Huf Haus, and Hanse Haus. Assembly of an entire house in 1-2 weeks implies little or no rework.

  That's for the woodenframe. Excluding installation of wirong, pipes, heating... At which point we are back to manual installation, and welding where needed, of those things.
