It's actually not so. Tracking isn't that challenging in this day and age. The plotting of intercept courses isn't all that tough, though finnicky to arrange, and is expensive, though I highly doubt as much as I think you are implying. Again, I freely admit that I am over-simplifying. But it certainly can be done.
Also, getting usable satellites that are further out means lofting heavier satellites, further... which is itself more resource intensive. Bringing them down means putting a smaller and lighter thing into the same orbit, or an intercept course, which is less resource intensive than the launch. Simplistically speaking.
