> Yes, being drunk seems to be like removing your psychological self-defence, which builds trust, especially in a high-stake business relations. But it's not the only way to build trust, for sure, and definitely doesn't justify the damage alcohol does to the body.

Not trying to convince you to change your mind, but you seem to be missing some information: I'd wager that for the vast, vast majority of people, "drinking alcohol" in a typical way rarely means "being drunk." At least in US culture, those things are only synonymous for certain specific groups, like people to whom drinking is novel (think college students) or alcoholics. Your mileage may vary, of course, and lots of this is my perception, but "benefits of drinking" and "benefits of being drunk" are definitely not the same conversations.
