I agree with all you are saying but hope one point can be made more clear and that is; "Heaven forbid that it collide with something and produce a debris cloud that can never be fully cleaned up in our lifetimes." At that altitude the time for natural orbital decay is not within our lifetimes by tens of thousands of years. If mammoths and saber tooth tigers littered up there it would still be a hazard to us today.
