Good codes of conduct can work to set expectations in certain social settings. While it's not illegal to smell bad, a conference may want you to shower before returning to the conference. A clearly stated code of conduct can enforce the professional standards of that conference in order to make all attendees of that conference feel comfortable. The problem here isn't the existence of the code of conduct, it's the combination of the lack of clarity and the hypocritical lack of following its own standards set from the conference organizers.
