In the past, I've had some dealings with specialist programs aimed at providing rehab to doctors and lawyers who've screwed up and had their addictions come to light. It's generally regarded as a truism among the people who work in such programs that addiction treatment for those people is MORE difficult and MORE intractable because of their belief that they're smarter than everybody else. They've generally built up a whole pile of rationalisations for their behaviour, and because of their income, they've often avoided the kind of rock bottom that most people are confronted with prior to rehab, so they see themselves as somehow 'different' to the typical addict.
And of course, we've already seen Nick deploying these rationalisations when he talked about his experience of rehab. Because this was a non-specialist rehab, the (reformed?) wine moms that run the place probably haven't had extensive experience with this type of addict, so they may well have been suckered by Rekieta's wine mom charm offensive. But I suspect that the judge in his case is all too well aware of the lore around these issues, hence his rebuke to Rekieta's bullshit about how 'smart' he thinks he is.
