In any race course where you are not in a tuck coming out of a gate, I would think you would want that one hard pump to accelerate the skis out of the turn.
It seems that your argument is about line, in that the line used to make a turn and pump is not as good as the line that is the fall line. However, that's not a valid argument in a race course. Your statements have made it sound as if you are saying that using muscular effort to aid acceleration when coming out of a turn will not work and will not accelerate the skis out of the turn, so you may as well not do it. If I'm taking the exact same line coming out of a gate, and I pump to create acceleration, I will go faster than if I don't.
Also, in some cases, such as flater terrain, as stated by others, it can actually be faster to make turns and pump the skis then it would be to straight run the fall line. Not only will the skis be traveling faster, but if done properly (not too big of a turn), you can reach the bottom of the hill before the person straight running. It goes back to that skatboard analogy. If you have a very gentle slope, and just point the board down the fall line, it will not go as fast as if you go back and forth and pump. Back when I used to ride a skateboard, I could make it accelerate up hill doing this (granted, not very fast).
