Again, that's not the point. The point is that Bill Cutter isn't going to be recognized by the game. Wouldn't it be better if he were recognized by the game? What if the game gave you extra perks, or certain NPCs reacted differently to him because of your self-imposed rules?
Unfortunately, such a system doesn't exist in New Vegas, making self-imposed rules meaningless in terms of the game world and how it reacts to your character.
