While anyone is free to run a structured training program in the training arena, the training arena does not in one bit simulate the main arena enviroment. People used to flying in the training arena are caught with their pants around their ankles not knowing what to do.

I agree with your sentiment, Ack-Ack. One of my favorite sayings is "Practice doesn't make perfect, perfect practice makes perfect." Practicing improperly only results in the reinforcement of bad habits.
The thing is, I don't think the main benefit of having a newbie arena is necessarily increasing the capability of the individuals in it. Sure, those who are inclined to do so will seek the resources to get better.
What the newbie arena would do instead is give people an environment where they're not going to wind up running into a squad of top-shelf sticks and getting slapped around repeatedly. Ideally, they'd be in an arena with some people with similar skill levels to themselves, and have a chance to get a feel for flying around and shooting at people and see how much fun it is. Obviously, you're going to have the dolts who are experienced flight simmers running around slapping them down, but it should be possible to police that for the most part by looking at score etc.
Now of course, it's only delaying the fact that as you say, nothing can prepare you for the MA. If you go in there having never been in a similar situation before, you're going to spend a lot of time reappearing in tower wondering what got you. The thing is, if you had some of those warm fuzzies at first in the newbie arena, some people might be more inclined to tough it out and learn what they need to to get better. Some won't, will still think the guys that slapped them around in the MA are cheaters, and leave in a huff.
Would there be enough of the new people who would find it attractive to go to a relatively unpopulated newbie arena versus logging in with another 200 people in one of the MA's? I don't think so, and believe that's quite possibly why there isn't one, but I could be wrong.
