So the problem is dealing with the 3rd party, to get the authorization? I hear your frustration, but I am still not understanding the issue exactly.

I don't like the intrusiveness of the authorization process, or the "watchdog" role of the insurance company, which is why I don't use insurance for my therapy (also, there is a huge deductible, so I would be paying cash anyway).
Between having to 'prove' I need the services and the limits on treatment and providers, I suspect the whole idea is to discourage a person from using the benefit. It looks good on paper ("We offer mental health benefits") but reality is something else.
