The idea of isolation comes from the deliberate refusal to allow them to remain with their families and be raised among ordinary people. They must be raised with the Jedi, live solely among the Jedi, never have a family outside the Jedi. They do mingle among non-Jedi occasionally it seems, but that's as far as it goes. I need to re-read that conversation again, it must be in Stealth or Siege. I haven't read the JA books, I'm not a Jude Watson fan at all; but Anakin and Padme hitched a ride on the refugee transport; I would guess that isn't too uncommon. But their temple was a literal "ivory tower" and seemed set up almost like a monastery, only in order to join a monastery in RL, monks must be old enough to know what they're doing. The Jedi had the exact opposite policy. Also on the inflexibility, yes, the Jedi allowed Anakin to be trained (grudgingly) but they had a "one size fits all" method of training. I've worked in the public schools for almost 13 years now and there is a lot of focus on differentiation--IOW, teaching all students in exactly the same manner would not go over well, nor should it, when we're dealing with individuals with unique personalities and learning styles. The Jedi seemed to have no respect for that, as Obi-Wan was the only one who made even remote adjustments in his methodology to take into account Anakin's background and personality. Or should I say he tried to do so; he was overruled by the Council in most of his efforts.
