I think it's a little like losing weight and other food issues :-) You gotta eat to live and grow to survive.

I don't think anyone "needs" therapy, it isn't up to someone else to decide whether an individual wants to give therapy a try or not. Sometimes the individual just wants a "companion" to help in the struggle, to witness it and give some pointers or just an indication that, "yes, you appear to be spinning your wheels, have you tried. . .?"

I don't think there's anything wrong with another individual's way of living; it may not be mine and it may not appear to me to work well for them (and may or may not actually work for them). Therapy is only one way of working with one's life when one feels stuck. In my best years in therapy I enjoyed and worked hard at therapy like I would have a job or school or anything else in life that I deemed important to me.
