No, this does
Let me take that straw man of yours and set him on fire.
There's no need for manned flight to asteroids or comets, and very few are proposing using them for their resources.
The need is to be able to either blow up or divert the next one of these before it hits.
The public would rather see NASA spend its money on ensuring their safety than on sending a few men to Mars.
