Even in the current geopolitical context I would preferred the US to get out of our hairs. That would probably smack some sense into EU in regards to a shared defense.
Weirdly enough, none of our politicians, or yours except trump, seems to be super into the idea. I guess NATO yield some dividends, too?
But I was more thinking at resilient community of civilians. Living in village / small town that are livable without that much inputs from the “grid” and without driving miles and miles( because they were build before that support system even existed )
Also, communities where living together is seen as normal, not some hippie or comunist idea.
As a result, elder citizen can lives longer there without need for adhoc care. It’s cheaper to raise kids. Food is cheaper and of better quality. ( farmer markets are where poor people buy food, for instance, not a fancy place for organic ware )
My observations are of rural US and rural France. Of course I’m biased.
