The implication as I read it is that you can have all the intent in the world, but if you don't have technique, your intent isn't going to get you anywhere.
Surely, better technique (that is, higher skill level) allows you to "realize" your intent to a greater degree. No argument there. But your intent still absolutely dictates the exact technique necessary. If your intent is to stop short and quickly, you will certainly employ a different technique than if your intent is to carve a pure arc--for example.
And most significantly to this point, and where I tend to disagree with your words in the quote above, your technique will differ given these two opposed intents no matter how much or how little skill you have. Yes, you'll do it better either way, with more skill. But "defensive intent" (stop, slow down, avoid that, stop going this way, and so on) will always produce fundamentally different movements (technique) than offensive intent (go that way, go faster), even if those movements are done with little skill.
You can prove this easily and simply. Picture a beginner who has just put his skis on for the very first time, standing on the flats--nervous, out of his element, and possessing very little skiing skill (I won't say none, because many other activities like walking, skating, and so on do transfer positively to skiing in many ways). Stand off to the side of this person, and tell him to "come here." Watch his movements--assuming he's amenable and doesn't owe you money or something, all of his movements will tend to move toward you. He'll turn his ski tips--the one closer to you first--toward you. He'll "project" his body toward you. He'll even tip his skis a little in your direction. All of these are the very same movements of high-level offensive turns, even if they are done clumsily and with rudimentary skill. He might even cross his skis and fall. But at least, his movements were all the "right" movements, regardless of how rudimentary was the skill behind them. His intent--to move toward you--dictates that technique. Practice and greater skill will make it work better.
Now imagine that same beginning skier this time actually owing you money when you call him. This time, he doesn't want to come toward you. His intent is to avoid you. He still has very little skill, but his movements (technique) will be very different, if not diametrically opposed. Intent, again, dictates technique. Intent does not produce skill, of course, but it clearly dictates technique.
"reifies" (allows you to realize) intent, and the more skill you have, the better (of course). But intent determines the fundamental characteristics of your movements. As I've so often pointed out, no amount of skill and technical expertise will make you carve a better turn when your intent is to stop quickly, or to avoid a sudden obstacle in your path, or if you are simply unwilling to point your skis downhill and gain gain speed when you start the "turn." Failure to consider this truism is the cause of perhaps more ski lesson failures than anything else. The student asks for "better speed control" or something like that, and the wise instructor (accurately) says, "to make a better turn, you need to release your edges, let go of the mountain, and point your skis straight downhill." The intent ("slow down!") and the technique here obviously conflict. And the intent will win, every time! To carve a better turn, you have to want--deep down in your core--to go faster when you start it, because obviously, going faster is what you're about to do when you start a new carved turn.
And with that, I think that this little detour has brought us back to the original topic: how to go faster. You have to want to go faster, first! Ironically, and perhaps paradoxically, if you go "as fast as you dare," you have reached a speed at which (by definition) you no longer want to go faster. Your intent becomes defensive, and your technique will reflect that defensiveness, no matter how much skill you may have. So the paradox is that, if you want to get "better" and make "faster turns," you obviously have to want to go faster all the time. And the only time you or I or anyone else wants to go faster is, of course, ... when we're going "too slow." So, to get faster, you have to ski "too slowly," all the time!
Neither "too slow" nor "too fast" refer to speed, actually. They are states of mind. One person's "slow" will be kamikaze fast for another of less confidence. But no matter who you are--first time beginner or Lindsey Vonn--once you're going "fast enough" or "too fast," your intent will change your technique in fundamental ways.
