I’d say rather that role-filling isn’t necessarily a smart thing. Much of how humans interact is little more than negotiated role-filling. In fact, choosing to fill-roles can be quite useful and adaptive. I don’t think it’s useful meaning of the word to consider 95% of the human race to be insane. Jumping into such choices without sufficient introspection, thought and intent is likely to lead to poorer outcomes, of course.
