I'm wondering if there's some mis-understanding in this thread about who's leaving the court, and why. The violation relates to players on the court, during play. What the rules committee is trying to address is the situation where, as an example, a player goes OOB to aviod a screen. The committee expressly said the game needs to be played within the confines of the court, so it is considered an unfair advantage if a player uses more than the designated court area. Examples of "authorized" leaving would be diving OOB to try and save a ball, and stepping OOB to administer a throw-in. Another example would be after a made basket, more than one teammate of the thrower may be OOB along the endline for the throw-in.

Displays such as what deecee mentioned, a player walking off the court in protest after a foul call, can still be considered unsporting and therefore a technical would be called, not the violation.
