I also suspect that many of the young people who can afford and are interested in many of these sorts of hobbies have, at least incrementally, tended to shift more urban which makes them impractical absent some shared club/store space. When I first got an apartment after school--and pre-digital photography--I tried doing home processing in a half-bathroom and rapidly concluded that was for the birds. (Even after I got a house, there really wasn't a suitable space and then digital photography came in.)
