I feel like the author is describing a scenario that is extremely rare (someone please correct me though if I am wrong).

What a lot of these parent-forums don't understand is that the very act of going NC is a huge undertaking. It's hard to disown your family and cut away entire networks of people, especially when you are young and just transitioning into your adult life. It makes a lot of things very difficult, such as small-talk (when people ask about your family), holidays, special occasions, etc. Not to mention the lack of financial support (even if you lacked it before, you guarantee it is 0 during NC), which can be really hard to endure in this economy. Why anyone would go through all this trouble if they didn't need to is beyond me.

A lot of us who've gone NC have done so because we ran out of options. We didn't want to go NC. We wanted to fix the damn problem, but our parents made it impossible. Going NC (especially when you are young) is a lot like amputating your foot during a race because it's become infected beyond repair. The idea that we'd cut off our foot willingly in some different context feels like mental gymnastics to me.
