One important factor is that many alcoholic beverages taste great and are a way of enjoying life. I don't think "zero because that way you'll live longer" is the be-all end-all of arguments. What if the same hypothetical argument was made of sex [1], "don't do it and you'll live longer", would that be a pleasureable way of living a longer life? [1] which may not be true of humans, but it's not scifi either. Some species, like octopuses if I'm not mistaken, die after breeding (for the male this means "sometime after having sex", for the female it's more complicated).
