I find it to be a happiness trap myself, it puts you in a gated world which doles out satisfaction, but you can never achieve long-lasting emotional and physical well being. When the person wakes up at 40, 50 and finds a life of little achievement from what they once dreamed, now it being too late to truly make big moves... similar to people who spend all their time functionally drinking or smoking weed. Yes, you can survive, but when your working days are over and you find you have no skills or abilities or hobbies or close relationships, what has your life been for?
I've had a parent that after a lifetime of working and providing and chilling out by having beers exit the workforce and suddenly having nothing to attach to. I fear the same for my friends.
I would say that my love of alcohol and wine in particular would qualify as an addiction; but at the same time I'm able to hold down a job. My bosses are happy with my work and I do feel fulfilled with what I've accomplished at the end of the workday.
I'm sure psychologists would have a field day with me but as far as your original question I've offered my input.
E: to amend that, I do have a small group of close male friends but I do have trouble finding an intimate relationship, due to other (unrelated? maybe?) issues with women.
I realize I might have taken this a bit too personally and lost track of the overall theme. I do agree that judging the effect of certain vices could also be judged by more than just "does it affect your livelihood".
