Drinking is taking a nosedive because larger segments of society are shut-in losers, who are not engaging in real-world social spaces which are lubricated with alcohol. That's 95% of the reason, the rest is people smoking when they would have been drinking.
The fall in alcohol consumption is directly tied to a fall in socialization writ-large. That isn't a win, it's a tragedy.
Yes, your entire post screams "older generation knows better, newer generation stupid losers" in unifying accompaniment with my initial caveman comparison. It's always interesting seeing the divide of generational vs cultural values from the point of view of people in the country, and the absolute insistence that their values represent one side vs representing the other. If you're observant, you get to witness in real time the cold and deafening silence of society moving on and losing interest with whatever hill-of-the-week people want to dramatically die on through over performant thrashing about. I mentally frame this timeline and context to be the equivalent of a child tantrumming in a grocery store while everyone else is just focused on shopping and going home, except I get to stop and point and laugh every once and a while in moments like this one. The death of stoner culture and commercialization of THC as a product instead of a lifestyle was pretty similar.
