I think you are leaping way ahead of yourself. It is one thing to set up exterior walls its another to build all the insides which is where a lot of the work comes in. There is also preparing the site for building the first place including preparations for a foundation. Same goes for buildings with steel support frame structures. Pre-fab housing is not new either and it hasn't managed to collapse the construction jobs.

That right there is the most exciting thing for me so far, and something I've been thinking about for a while. Even if it turns out that there has to be people there while it's being build, such printing machines would cut down on a lot of initial personnel and equipment requirements, I think.

Seems like cutting jobs would be a legitimate reason to oppose this sort of advancement then. But I think it's more likely the jobs will shift around some. People don't stop needing houses to live in, after all. In any case, I don't think this sort of thing will happen particularly quickly.

Expergiscēre cras, medior quam hodie. (Awaken tomorrow, better than today.)If there was a way to make cosmetic car parts with 3D printers to a quality sufficient to mimic original components, people who restore and maintain old cars would be quite interested. There are many parts, especially for more obscure makes or models, that are nigh-on unobtainable these days. Often manufacturers, especially American, would change those cosmetic parts annually so the original supply for an optional accessory may have been tiny. E.g. 1967 Ford Thunderbird passenger-side mirrors; they only made five hundred of them. Ever. They're practically unobtainable these days, but the demand for them is too low to make manufacture of them by conventional means economically feasible. If they could be 3D printed, it would be wonderful. They were fairly roughly cast from pot metal originally, so I think the strength of 3D metal printing would be quite sufficient.

3D Systems and Stratasys were aimed at two different markets. The consumer printing market isn't really here yet, so 3D Systems doesn't have a big audience. Stratasys has been doing much better with the business market, which makes sense. I suspect as 3D printers gradually get better and less expensive and capable of using more materials and printing faster, business will be the first to adopt in large numbers, with consumers only eventually coming later, once people get the idea that 3D printers are actually useful. And that one will take a while.

I rather doubt it. Look at the article, they've got a crane lower the wall segments into place, with at least 3 guys on the ground. Might cut out a few jobs but they'll be around.
