your gray area. not mine. you want a gray area, i consider your system naive.
again, alcohol use is an exponential curve ending in death.
as inhibitions fade, you drink more, and vice versa.
if you can stop at 1 or 2, then great. but the potential for tragedy is always there.
its like buying a gun. you're more likely to shoot someone if you have access to a gun. moreso than someone without a gun. once you've taken that step, you can be dangerous, regardless of your intentions.
Again, you're grossly simplifying, acting as if all people drink for the same reasons. Lots of people can stop at one or two. The alcoholics are, in my experience, the minority. The occasional binge drinkers form a larger percentage, as do the "glass of wine in the evening" types.
Theres a potential for tragedy walking down the street.
