I have to agree that the sentiment seems strange to me. All my employers have had multiple receptions, celebratory drinks or lunches where alcohol was served and consumed. No one ever got drunk or misbehaved because of it. People are smart enough to be moderate in their alcohol consumption. Note that in my country (Belgium), alcohol consumption at work is illegal, so these events were always after work hours or during lunch breaks. Technically, people had to badge out before consuming alcohol.
