The comment you are responding to is wondering about what might be "healthier" in general? It even acknowledges that it could work "worse in others".
I do not think it's a stretch to say that some people deal with adversity and misfortune better than others, and not everyone ends up with mental health issues after very similar experiences!
So without getting riled up, my response to the GP would be: "no, it wouldn't, because even if that works with simple majority of the population, it might leave 49% of the people messed up — let's not move away from the individual approach!" (I don't have actual numbers).
