What was (is) the purpose of the division line?

The game needed a proper balance between the offense and the defense so the amount of space in which the offensive team could operate was reduced. This restored the balance and gave the defending team a legitimate chance to steal the ball.

I agree with this description. The 6v6 discussion has actually been quite interesting. Years ago, whenever I had a player who didn't like to play defense, I would tell them they went to school in the wrong state -- and would end up explaining the "Iowa Girls Basketball Rules" at a high level.
