Congratulations, kintsugi, and welcome! I read Carr's book after I had been sober awhile, and I found it helpful and eye-opening. I shopped around through various approaches to sobriety --- SMART, Lifering, AA & working the steps, and reading tons of books. In a way they all worked, because I stayed sober throughout, but some approaches didn't really fit with my values and worldview, and caused cognitive dissonance that would have been hard to live with long term. Ultimately AVRT/Rational Recovery is the thing that made the most sense to me and to which I can comfortably make permanent commitment. That being said, I learned useful things from almost everything that I tried or researched.
I think I understand what you were trying to say. I think freedom from alcohol isn't a one-approach-fits-all proposition. We have to find the thing that "clicks", and I'm happy for you that you found it.
