In our society we don't value communication and feelings enough, and most important of all, we are not really taught how to understand them, manage them, cope with them. In this sense, everyone can learn something from some kind of "therapy". In fact, precisely the people who may not need therapy, as you say, are not exposed to certain useful concepts. It's a bit like saying: I went to the dentist and he told me to do this in order to improve the way I brush my teeth. Why am I telling you this even if you don't need to go to a dentist? Because prevention is for everyone.
