Good point, but those two points near Jupiter have already been observed full of junk, IIRC. I'm not modeling the problem well enough in my head to be sure I understand why.

maybe the law of averages accounts for it. eventually, a collision between two bodies may stop their motion in that location? I have a hard time rationalizing it, because of the vastness of everything, but it's the only thing I can think of.

Gravity Sink?
But what causes the junk to stop?
Perhaps it settles in after several 100 millon orbits over a million years....
