This is not likely because ANY significant presence
of dark matter within or near the solar system would
disturb the orbital stability.

Not if it were uniformly distributed. Of course this paper says the distribution might be displaced by collections of matter... which makes the problem you allude to.

Thus the problem with dark matter is not just to
explain its nature and composition but also to explain
why it is so non-uniformly distributed within galaxies.

Easy. It is primarily a "calibration error".

But if we don't look for exotic matter too, it is not Science.
