The argument isn’t that basing sentencing on physical attractiveness is unfair because attractiveness is randomly distributed (“less a given”), it’s that it’s irrelevant a priori; accordingly your argument misses the point. In contrast: IQ and grit are by definition supposed to measure those traits which are relevant to success; fwiw they are NOT considered completely fair, but that is because of the extent to which many instruments end up measuring “belonging to a certain cultural group” instead of those relevant traits.
