You're completely correct; however, the occasional partaking you describe is equally applicable to other addictive activities, be they substances like alcohol or marijuana, or purely behavioral addictions like gambling or MMOs. Some people can do it once in a blue moon, some people can sustain doing it every weekend, and for some people it becomes an unhealthy dependency. In all cases, I don't think there's anybody who wouldn't benefit from additional mindfulness. If such behavior becomes problematic, it's a case-by-case determination as to whether moderation or elimination is the better strategy. (I personally find it easier to eat zero junk food than to eat it occasionally, but I certainly don't begrudge anyone who can moderate successfully.)
