It's your choice. Surely you'd want to not have a psychological and physiological dependence rather than fixing the deeper issues.
Why are you being critical of his plan for his own health? He already discussed his interest in doing CBT. There's enough antagonism about the use of psychiatric medication without having to deal with it on this forum. It doesn't sound like this is something he's jumping into after one bad week.
Therapy can be a very beneficial tool, but is not the be-all end-all treatment for every person suffering from anxiety and depression. Qualified therapists are not accessible for everyone. The therapist I tried was not a good fit for me at all. Also: I was attempting so many anxiety coping tools: exercise, meditation, CBT strategies....and I was so anxious, so overwhelmed I could not manage these things successfully. I've been on Lexapro for two months, and these techniques are falling into place. Nearly every day I'm taking some time for self-examination to see where I'm at with my anxiety and with my life in general, where I'm at and where I wanted to be. Previous to the medication, I was just trying to hold my head above water and get through the day.
Surely that diabetic shouldn't be physiologically dependent on their insulin....
Surely that asthma patient shouldn't be dependent on that inhaler just to breathe!
