If we change the analogy we get a different answer. Everyone agree that murder should be forbidden, but we don't want mob justice to go around lynching suspected murderers. As a society we have laws. CoC as extrajudicial rules get judged based on their benefit to extend existing laws and append additional law enforcement on top of already existing law enforcement. If the result is bad and the additional rules causes more problem than they solve then they should be discarded. It does not mean all extrajudicial rules are bad but we need to ask if they are needed, serve a good purpose, measure the outcome, and be ready to discard them when the situation calls for it.
