Sarcasm my friend. Please read the thread.
What you are saying is correct, but has no bearing on the fact that cutting calories IS enough... just not ideal. For many patients exercise is a deal breaker. Thus, I have no qualms about recommending calorie cutting alone to lose weight. Would it be better to exercise as well? Yes of course. But more often than not people use exercise as an excuse not to cut enough calories off their diet... and of course then they go on to exercise much less than necessary... and don't lose any weight. Seen enough of that.
