Tayopo welcome to the forum.
Not everyone practices point shooting or trains at all. To say that point shooting will work in all circumstances in the home is far from true. In my home it is approx. 17 yards from my bedroom door to the far hallway door across the living room, point shooting won't quite cut it for most at that distance.
I train to fire reactively at contact distance all the while creating distance, bringing the gun up and fighting my way to the sights.
