It might actually last longer being stationed at L2. Yeah, it'll drift away and fall into the orbit of some massive body. But if it were at L4, L5... seems to me it'd eventually collide with all the natural rocks that are also stuck in L4/L5.
I'm not sure if this is true or not. Just conjecture on my part. I know that asteroids naturally get stuck in L4/L5. Seems to me, over geologic time scales, James Webb might be safer just kind of floating around freely rather than in the "rock pit."
