On the latter part we agree.
However, Morrison and his lot are justified in their focus
on Near Earth Asteroids. In a technically advanced 25th
century world we may live up the science fiction visions
given in the planetary defense papers you point to, but
to-day we need to limit our effort to the bare essentials.
That is, detect, detect, detect! And should a Tunguska-
sized rock be identified to plan a visit, let's refine the
orbital analysis, pinpoint the impact area, and evacuate
it in good time. No need to send the marines or Bruce W.

On the danger from BAF ( the Baptistina Asteroid Family )
Bill Bottke states unequivocally: "We are in the tail end
of this shower now. Our simulations suggest that about
20 percent of the present-day, near-Earth asteroid
population can be traced back to the Baptistina family."
That makes BAF a greater threat than SW3. Maybe Ed Grondine
should direct some of his concern in that direction?
