I ended up falling into using a surface for my travel and it’s been surprisingly good. I have surface pro 7+, and it’s small enough to use on an airplane seat, has good battery life, a great screen, and can do some limited gaming. With an upgraded drive (1TB for $100) for movies and low end games it’s a great little computer. They also run for 200-400 dollars on eBay.
Your 3d printer doesn’t have other utilities to accommodate. The printing is basically just the walls. Every other utility (Power, water, sanitary, HVAC, foundations, windows, doors, metal fabrications, networking etc) are all still done by people, all made with options made by other manufacturers.
Your printer also uses quick setting thermoplastic, not a concrete slurry that needs to set over the course of days instead of fractions of a second.
This and typical FDM printing are related, but truths about printing out a plastic trinket don’t necessarily translate to large concrete structures.
Funnily enough, porn is sort of the canary in the coalmine for free speech. Their use of banning it will be through defining what is and is not obscene. If they can get a case run up to the supreme court, who then confirm that this self expression is obscene, that opens the flood gates for them to freely define what self expression is obscene and ban it or send people to jail.
From there it’s a small step to calling something like a dissenting political opinion obscene.
