The Amish have a solution that works for them. There will be a boom in copycat communities at some point. It might be fun to start one. It could be argued the global warming cult is an Amish start up. Its early leaders are living large.
That is certainly one possibility.
But the Amish live as they do because they believe it’s God’s will.
Probably more difficult to live in a similar way just as a lifestyle statement. But I assume quite a few people would do so.
John Ringo has written a series of novels (Looking Glass) in which a beneficient Skynet type computer runs the world and gives every human what we’d considered godlike power and wealth.
Then the system breaks out into civil war and everybody is back to middle ages type tech.
The writing isn’t all that great, but he extrapolates some interesting ideas about how people would live in a world where there are very few restraints, material or cultural, on anybody. One of those ways is for people to ostentatiously pick a period of history and pretend to live in it. Problem is they always know it’s a pretense.
