A few problems holding a solution like that back right now: 1) It takes a ton of fuel to change your orbit once you're in space, and space is _really_ big (even just the orbital ranges we're talking about). It's just not currently feasible for a ship like that to capture debris and then use _more_ fuel to bring it back down. 2) Relative velocities of some debris are so large (and they are so spread out) that it's not yet feasible to capture it and bring it back with any current approach. Dead satellites are mostly dangerous for the scattered debris they _might_ become if something hits them/they bread up. So while bringing them back is important, it's not as immediate a danger as things that have already broken up. Basically, we don't have any approach that would make a major difference, even if money was no object (which it is).
