Quote:It's not that alcohol is good because it has been widely used for thousands of years, it's that it is firmly established because it has been widely used for thousands of years.
I'd argue that it's not alcohol use/abuse that's been established for millennia (or longer), but rather something fundamental in the human psyche that leads a certain -- and not inconsiderable -- portion of the population to seek escape in some psychoactive chemical or other.
For cultures of Western Europe and of the steppe (perhaps -- I dunno enough about the recreational practices about people east of the Urals to say), this was largely alcohol (plus caffeine, when it was found out, and nicotine, when it was found out, and pretty much anything that came out of early drug labs). For other people, it was marijuana or something else. Regardless, everyone on the planet (or a certain percentage thereof) is driven to play with their brains.
You're willing to make an allowance for alcohol based on cultural precedent. I appeal to a deeper familial precedent -- that of the human species. To try to advance the species without allowances for inherited traits is madness: all you do is develop a society that is at odds with the animal natures of the people it encompasses, protects, and influences.
