It is indeed puzzling how intuition got such a bad rap with the investment community. Ask any discretionary intraday trader and they'll tell you it's an absolutely critical skill to possess, which is developed through tons of repetition WITHIN an already existing analytical framework. I think that is the key point that most in the "anti-intuition" crowd miss-- you must develop the rigid, analytical framework ("a system") to contain the intuitive when it comes to trading/investing. Only then does intuition become a truly irreplaceable asset.
