I think sometimes correcting the symptom leads the person to realize that they are doing that and correct the problem. It's easy to behave like a jerk without realizing it and a lot of people who come off as arrogant don't imagine themselves as being so. If you tell them to respect their coworkers, it doesn't have the same impact because it not actionable (they already imagine themselves as being respectful).

That's why banning specific toxic behaviors work, it encourages introspection for people whose bad behavior is unintentional.
