I always though the basic hypothesis is the other way around: the populations with low alcohol tolerance used methods other than brewing to generate safe water

I always though the basic hypothesis is the other way around: the populations with low alcohol tolerance used methods other than brewing to generate safe water (e.g., boiling as in tea) and hence no selection for alcohol tolerance.
If there really is a selection against alcohol, why did that not kick in outside Asia, too? The selection mechanism postulated would need to be fast... are 2k years or so really significant?
