Alright is there another hypothetical you wanna take way too seriously or just mine? It simply said whatever I want and thats what Iβd want. It didnt say small scale, or any other restrictions. And if you really want to know Iβd jack Greer Arizona, which as far as I know, Molly Butler settled there first.
You could probably fit it all into AZ. Youβd still need oil wells and refineries somewhere; there are still plastics involved. And rare metal mines - mines in general, for metals, so youβd probably need outposts in other states, and then a rail system to get materials to AZ. Feeding people would be hard on AZ, though, so youβd definitely need to clear forests in the Midwest and put in a bunch of factory farms to produced food.
The US might have enough of everything to support this, although I suspect some rare metals would be difficult to source, as many of ourβs comes from other countries. However, maybe you could stockpile enough to last. You need the rare metals, but maybe a few tonnes of processed would be enough to last?
