To put it in military terms, you have a siege, but you can't bust into the castle.
But it is richer because the game is far more subtle with the rule than without.
My guess is either you are trolling, or simply unaware of the beauty that results because of this rule.
My position on this is simply that the game is much richer and more interesting as a result of this rule. As a result, it should stay.
The end-game in particular is far less interesting without stalemate.
Much richer? Yes, when the losing player has the opportunity to win even though he is in a position where there is no way out. It's all about perspective and preference i guess, IMO if a king is captured and has no way out i.e. stalemate, why should there be a draw? The king has nowhere else to go and the player has no options left. There should be a win for a stalemate, not a draw to make the game "richer".
