Sure not all fermentation produces alcohol, but many fermenting organisms do.

And of course it’s observational bias, I said that I personally can’t imagine how the culture of these countries would be without alcohol, though I’m sure people would get along just fine (we don’t need alcohol to survive after all). Just saying that not everything needs to be banned, otherwise we might as well ban sugar and salt as they probably kill just as many (or more) people as alcohol.
