Skiing's Three Dimensions

Whenever I read an article on ski instruction, I'm always struck by the absence or the lesser role of speed, a fundamental component of that sport. In fact, alpine skiing is the product of just three essential components:

1. Speed and gravity, the essential part of alpine skiing. Not only do they create the necessary momentum critical to gliding on the snow, but also provides most of the thrill skiers come to enjoy. 
2. Body positioning, involving mostly feet, legs and to a lesser degree the upper-body and arms. This sets the stage for changes of direction and speed control. This is also the foundation of the ski technique. 
3. Muscular output, mostly from a passive type. That essential effort is calling for the thighs and the abdominal muscles to sustain and oppose pressures brought forth by centrifugal forces, terrain jolts and varying effects that call for muscular resistance. 

Of these three elements, speed is the most important as long as the skier has mastered the minimum amount of technique required from the sport.

This is why I can't help but wonder, why speed has to be the looming elephant inside the ski room?
