Total fairness implies the existence of a game. You can only be fair with reference to some rule and some measurement. The universe on one level seems absolutely fair: we're all within exactly the same, apparently extremely consistent laws of physics. If we don't like this and find it still unfair (I find it still unfair, like almost everyone), then we create a new game within the game, and do our best to adhere to it. If the new game within the game became perfectly consistent, why, then wouldn't that be another universe in simulation?
