It isn't that different, really, than the Merlin crowd who romanticize the living conditions and superstitious batshittery of the Dark Ages. Or the strange Teuto-Germanic romanticization that sprang up around Nietzsche and Rudolph Steiner, and was twisted up into something truly perverse by Wagner and the Nazis. Or the representation of Samurai-era Japan as being some sort of wonderful illustrious period of enlightenment. It is interesting how people are drawn to places and times out of a sense of nostalgia for what never existed, conveniently overlooking the 'nasty, brutish and short' business.

(Besides which, any form of movement, even mechanical movement, must factor electricity since friction begets it.)

Even so, I see this fantasy as a representation of people's inner 'heaven world', something which is intrinsic and nonphysical, except in the sense of play. As with any romanticization, there's always the possibility that you get that Nazi effect of pure delusion and mass psychosis, but for most people, it's just a way of experiencing adventure and derring-do in the safe and harmless fashion of fantasy.
