Point shooting is fine - for ranges not exceeding 5 - 10 feet. If you're so talented & have unusually sharp eye-hand coordination & you can consistently hit targets at longer ranges, more power to ya. As Jeff Cooper said, bringing the gun up to eye level doesn't take much more time than point shooting, and you'll hit, instead of miss. And, you'll hit more effectively.
And, if you needed to make a shot with your friends or loved ones nearby, you'd be unnecessarily risking their lives by point shooting. In fact, a famous LEO & gun writer killed his partner instead of the suspect by point shooting.
