He's trying to connect going out and meeting people with the beer but the beer isn't the part that helps your mental health here. It's the socializing.
People are currently socializing less because social media is a (very crappy) substitute that is effortlessly accessible. I call it the fentanyl of social interaction. It's cheap and easy to access but the result is worse on all levels.
Take this conversation as an example. I reply to your comment and we're having a social interaction that might satisfy the need for human connection to a certain (very small) degree but nothing else will come of it. We most likely won't ever interact with eachother again. If instead we'd go out and discuss things with people in person we might actually make friends. Form lasting connections. Now I'm fine with my social life at the moment but if I wasn't I'd have a hard time changing it because people my age just don't go out much these days. Making friends got a lot harder than it used to be.
