"The pie rule only works when both parties are highly adept at their
assigned tasks." 

But adeptness at their assigned tasks is simply the ability to evaluate the
quality of a board position as being likely to favor one side or another,
and that's the essence of playing skillfully: choosing moves that create
positions where you have the advantage. It isn't unfair if the pie rule
leaves an advantage with the better player. The better player naturally has
an advantage at every point in the game.
