I think I understand what you are getting at.
For me quitting was very black and white. I enjoy black and white it makes sense. Math and physics make sense and create peace and ease...black and white. Philosophy, not so much as you would say.
Quitting is very black and white but recovery for me is about creating a sustainable life. This is about living in the grey for me - at least creating a sustainable life. Otherwise I end up becoming a monk. So there is lots of grey I need to deal with. This creates turbulence for me in recovery - balance - something I have never been very good with.
In terms of authenticity I am not sure the parallel is there between grey and authenticity. Certainly black and white decisions can be authentic as can grey areas of life. I believe being authentic comes first and then for me learning to live in the grey came second.
