I actually agree with you -- from the standpoint of socially influencing others who are not already addicts.

There is no true addict on the planet however (of any substance or behavior) who will hit "rock bottom", as they say, and moderate their addictive behavior due to shame. So I feel that some of the blowback you are receiving here is related to the notion (true or not) that public shame applied to addiction for the purpose of influencing non-addicts is equvalent to "giving up" on addicts themselves (and therefore not worth that cost).
