Why dont you just say the truth
The truth is that in your attempt to simply the game of baseball, you and those like you have adapted a numbers based system that you can live with, stripping the human element out of the game which you dont understand. The problem is that it takes an understanding of baseball, experience, and careful examinations to understand the subjective element. It takes time and fangraphs to understand numbers. Since the former you can never have, the latter's value you exemplify.
