If that's all the people you are referring to took from his books there was probably no hope for them anyway, at least at that stage in their life - it does sound like it's just immaturity you are talking about.

I think there are some good lessons for a young person in his playful curiosity about the world & the anti-authority message was mostly about not taking things for granted & not to be afraid to push further for a more complete answer and question things just because they have always been done a certain way.
