I wouldn't outright eject such a thing, however you should remember that the inventory issues are actually a helpful tool to newcomers.
You may suddenly want a the Battlemage's Robe. So you're off to Longstop to farm it. You have the option to run it by yourself and kill everything in your path using your mighty level 60 classes. However you think, hey this is a good time to get some experience on my level 33 whatever. So in you go, helping the queues. This poor new DPS class users waiting 3 hours because he has no friends suddenly gets accepted into Longstop after hours of gathering cheese for the main scenario.

So yes, it'd be nice to have gear earned be permanently available to you, but at the same time it drives the queues and economy (for sellable items). You gotta look about the bigger picture sometimes. It's not all about you, even if half the battle is about lookin' good.
