use of forearm on dribbler as long as it is collapsed (not extended) is legal as it is within the frame of the body while performing normal defensive movement and is not initiating the contact

Basically, you're saying the forearm that is legal is one that is held in contact with the defender's own body...as it must be to be within their frame. In that case, they're not using the forearm. If they've extended in any other position and contact occurs, it is not in a legal position.

The whole purpose of the arm bar is to impede the progress of an opponent. It has no other purpose. To say otherwise is simply silly. You can certainly argue whether the advantage it provides should be a foul or not, but you can't honestly say it doesn't impede the opponent or give the defender an advantage.
