In your opinion.

In my opinion, we certainly do not need to spend $110 billion to do flags 
and footprints on Mars right now.

PS - China will likely bring CAPS in for well under your tens of billions of 
dollars figure.  You can break it down into CZ5 launches, if you like.

BTW - the bulk of the impact hazard comes from comets, not asteroids.
