If it were sufficiently dense to fish, it'd be worth more to collect and keep it in orbit — that junk has a lot of high-grade materials and a lot of already-imparted momentum. Just[] move it all into a few large objects that can be managed as large craft, and the debris problem is solved, and there's a mineable resource already in orbit.
[] "Just" is doing some escape-velocity-class lifting there — all that junk is in such massively different orbital planes and altitudes that silly amounts of ΔV are needed to fetch each one and then to pull it back to dock with the new orbital junkheap.
