The Amish are (sort of) re-enacting a previous era of technological development. It seems to be hard work.
Imagine that the people who idealize the 1950s were to build re-enactment towns where they would have picnics on gingham and hand-wash red Thunderbirds. Or that postmodernism re-enactors would rebuild historical Xerox machines for period-accurate zines in a reconstructed Olympia, Washington.
Two challenges to living in a world that is technological and yet far from the leading edge of technology: 1) finding replacement parts is a challenge, 2) everything is more expensive because of the lack of economies of scale. Both of these seem surmountable in a post-scarcity economy, where dexterous robots can craft one-off replacements parts for old Thunderbirds or Xerox machines.
