I think everyone would agree that if you have the opportunity to use your sights you should. Everyone should have sound marksmanship fundamentals. It just needs to be understood that during spontaneous altercations that begin at conversation distance there is good chance you may not be able to "focus" on your sights as you do in training and the the truth is that the only thing that is required to put rounds on target is the barrel being in line with your attackers body.
Another human factor that needs to be taken into consideration is that we all like to see ourselves getting better. If we stopped shooting paper targets all together, eventually people would get bored and not practice as much.
