I think the concerns you raise aren't actually show stoppers for a lot of prefab housing that has been happening for decades.
Wood is a lot lighter than steel and concrete. And that has to be transported as well. So you'd have less cost there, not more. About 50% weight savings. That's a lot of diesel.
As for parts getting damaged. That's what insurance an warranty are for. I don't think that's a show stopper issue.
And there are advantages to producing prefab components in a facility that is optimal for that and climate controlled that has all the right tools, specialists, equipment etc. Also, pooring concrete in the winter is problematic. Water freezes. And it expands when it does so. Working with steel is a PITA when it freezes as well. It conducts heat very well. Construction sites aren't very active in the winter in those places that have them for this reason. Prefab wood components don't have a lot of these issues. You can still work wood when it freezes. And bang in some nails. Or drill holes.
It isn't a show stopper, but it is why site built it competitive with prefab unless (as is all too common) prefab cuts corners. Prefab because it needs to ship on current roads often has size limitations of the modules that limit how you can arrange your house.
