Some of them do. They are like that henwitted actress that came back from visiting some primitive village squealing in delight that she "poo'ed in the woods like a animal!" They are no different then the communist who will wax eloquent about how they want to live like a 12th century peasant.
The rest of them and these are the majority, think that they will live in solar powered manor houses and be the philosopher kings wisely leading their adoring subjects.
Of course it make no sense. No matter what they think these are not very "bright" people. Unless you mean "naturally bright" in the same way that the author of "The University of Hard Knocks" did.
