Man, it's weird being an American sometimes.
I do not drink. I am half Irish and half German.
Drinking is a _very_ weird cultural artifact from our past. It doesn't improve your life, it has been scientifically proven to not 'help you relax', and there may in fact be no safe amount of alcohol to drink; all the pop-sci headlines that say 'one glass of wine a week may improve your health' are really about studies that put the safe max at one glass per week.
From what I can tell, the UK is no longer subsidizing what is effectively a criminal enterprise that is centuries old.
What's especially American about this remark isn't the experience of consuming alcohol in public. What is characteristically American, I think, is the assumption that we can pronounce a thing good or bad merely on the basis of its effect on the individual, with no regard for one's relationships with other people. Drinking in a pub is a social activity, and the alcohol is a lubricant for that activity. Yes, doing too much of it can cause great harm; doing any amount of it could cause some harm; it does not follow that the thing is a net detriment to society, and that it should be banned.
It sounds like you don't understand what a pub is like.
Whilst this is definitely not what's it's like, this quaint video is all about the lineage of the pub in the UK, and explains the third-spaceness of them, which I'd argue still exists[1].
Pubs are so important for our communities in the UK, whether that's watching the game, seeing a friend's band, celebrating a birthday or just catching up after work.
Many of the parts of my life have been lived in a pub. If it's criminal, I'd happily be locked up. Or maybe lock me in, a sadly rarer occurrence these days.
Here is what I will say. Drinking certainly is not a healthy choice. However hanging out with your peers for a few hours a night in public certainly is.
Unfortunately I haven't found any place that cracks that problem in america, especially into the later hours. There isn't really a place for people to hang out and socialize without it being a boozy bar. As someone who doesn't really enjoy drinking I don't even really want to go to boardgame/chess/trivia nights at bars because I feel like I'm freeloading. ( I imagine any given bar patron is having 1-3 drinks per hour and potentially ordering some food if that is an option. I might order some food and have a soda...)
I assume part of the problem being that alcohol has the helpful side effect of greasing the wheels socially. Coffee houses that are open late are generally library like affairs, a lot of people sitting around on laptops or with books, any attempt to start a more social night is, in my experience, refused because of this.
With all due respect this opinion verges on neo prohibitionist alarmism. The social benefits of alcohol have been widely acknowledged and at a time when we are all spending too much time at home on our phones (arguably worse for health than a pint), communities need more social spaces. That place may not necessarily be a bar and it’s perfectly fine if you don’t wish to drink, but it’s a bit much to refer to a cultural product as a criminal enterprise.
