Have you ever noticed that extremely authoritarian parents often produce children determined to go to the other extreme? ("I'll never restrict the freedom of my children that way!")
And they go too far with leniency, and their children grow up and pledge not to let their children do all the horrifyingly dangerous stuff they got away with, or vow to set limits and be more involved as they wished their own parents had been; back to authoritarian, again.
Being a libertarian parent is hard to do, because it starts one way and ends another: clearly one must be an authoritarian parent to infants--ruling their lives in every way, but by the time they're 18, they have to have practiced taking responsibility for themselves.
Children are still growing and developing physiologically and socially, and need some guidance, but adults who behave as adults don't deserve to be treated lixe children: that's called slavery.
