I think of myself as relatively laid back, but these rules don’t seem that bad to me, maybe it depends on age? I probably wouldn’t let my <10 year old destroy a book, certainly not from poor impulse control, but I’d probably let me teen due so, particularly for an art project. And hitting people? It may not be totally abnormal to experience a little aggression, but I don’t really think it’s a parents place to let it go either.
