> if you use alcohol for social lubrication, you only screw yourself over by never learning how to truly socialize and let go of inhibition naturally
That's probably the least true comment in this entire thread.
I'm not going to say alcohol is therapeutic, but it is considered a rite of passage the world over for a reason. For many it's their first time experiencing lowered inhibitions and handling adult consequences. That doesn't imply an addiction will follow, but it is very likely to expand their mind regarding what they believe about themselves and their identity. Those questions are at the heart of social anxiety.
I really don't know where society would be without alcohol. Probably much worse off. People would have their heads so far up their own asses they'd probably be even more anxious all the time.
