Hmmm... I wouldn't put it that way. Also, keep in mind that we're talking about a spectrum here, with a custom World Cup race ski on one end and a rank novice ski on the other end. While the racer could ski the novice ski, it wouldn't respond the way that she needs it to respond while in course. So, if she gives a subtle wiggle to reduce and then increase the edge angle to miss a pole, the novice ski won't change direction at all. In addition, as Ghost says, it won't withstand the turn forces, either.
At the other end, put a novice on those race skis and they will respond to the slightest nervous shaking of the knees. Think about the pretzel contortions that the poor novice would discover!
In between are a wide range of skis that fall somewhere along that spectrum. One example is the difference between the Rossi Z9 and the Atomic B5. Similar target skiers, similar sidecut and shape, but the Rossi far more forgiving than the B5. As a result, when you really push the Z9, it won't be as precise as the B5. That's not to say high-end skiers won't ski and enjoy them (both Annie Black--Colorado Ski Instructor of the Year--and Nick Herrin do). In fact, they may actually help in some situations, especially if you're spending a lot of time skiing at the limits of your ability in freeskiing terrain out west.
Just some thoughts. I hope this gives you some grist for thought...
