You say moderation is a "dangerous idea", but don't you see Stanton's point is that this person died soon after leaving rehab with "strict instructions not to drink"? Is is not conceivable that emphasising the need for total abstinence to this person turned out to be a problem-maintaining solution?

You say that you've never seen a person benefit from moderation advice - well here is a person who didn't benefit from abstinence advice, for whatever reason. Shouldn't we consider those who repeatedly relapse after being given abstinence advice as potential benefactors of moderation advice?
