This may be akin to stating, "it's a terrible move to bluff on the river: you shouldn't shove with nothing," yet if we keep that ideology, then it suddenly becomes a +ev move. If it's always terrible to bluff on the river and nobody does it, then would it not be profitable to do so? Your opponents would never think that you were bluffing!
But in correspondence with bustabit, this will simply result in a sort of oscillation in the number of players.
