EMH serves the same purpose to economics as Euclidean space serves to geometry. If the hypothesis were true I can make a bunch of proofs and predictions in economics. The problem is when people confuse EMH with a fact, not an idea that is never really true in the real world, like an infinite perfectly flat plane.
