I don't think people are disputing that things can be useful without being perfect. My point was that when things aren't perfect, they can also lead to defects that would not otherwise be perceived based upon the belief that the tool was otherwise working at least adequately. Would you use a staple gun if you weren't sure it was actually working? If it's something you don't know a lot about, how can you be sure it's working adequately?
