It's not clear to me from your comments that you've read the article-- especially "It also seems strange to suggest naltrexone as an alternative to AA". Is it just because it's an 'evil drug' or am I missing something?

Also, I feel you're misunderstanding the "moderation" that the article speaks of. The AA literature you quote is about someone who is actively dependent in a bad way trying to moderate themselves. The "moderate drinking might be possible for some" line is about returning to a life of moderate drinking in the future.
