Because drag increases at the cube of velocity. So improvements in top speed
require huge increases in power. However in performance improvements short
of top speed increased power increses climb rate,
acceleration rate, and shortens takeoff run. Top speed, not so much.

The less obvious point is that since the drag determines he top speed for
any amount of power, the payoff for carefull drag reduction is higher top
speed at much reduced cost. And higher speed for any throttle setting.
