Traditions are often difficult to break. Take sights. Before firearms were invented, there were no sights. Spears were thrown and arrows were sent at a target using only experience, “Kentucky windage and Tennessee elevation.”

Even with the first firearms, sights were non-existent or primitive at best. With increased accuracy sights began to be taken seriously. Still, however, many did not use them and still don’t. I recently saw World War II footage of a US Marine looking over his sights, as he fired his M1 at the enemy in the Pacific, and so it goes, from hip shooting to point-shoulder “aiming.”
