We will all feel pretty foolish when an asteroid hits and causes hundreds of billions of dollars in damage that could have been avoided with a few hundred million in funding for planetary defense.
I believe our species had a reset or two from impact events. For example, right before the eyes of the world, there is NO WAY the Dynastic Egyptians built the Great Pyramid(s). No way full stop. They FOUND them.
There is so much evidence around the world that indicates a civilization that lived here that had greater, or just different knowledge, and capabilities than we possess today.
There is a recent discovery of an impact event found in Greenland that might date to 12,000 or so years ago. 20 miles wide. It is quite possible that it might coincide with the Younger~Dryas sudden cooling during the warming from the last ice age. An impact into an ice sheet miles thick. Floods would be epic...
The way things are going now politically, perhaps we need another.
Kidding aside, the concept of protecting the planet from cometary, or asteroid impact, is not folly, imo.
Why would an astronaut be an expert on defending earth from an asteroid? Astronauts are hands-on people who perform experiments, transport cargo, and repair things.
I would trust a professional statistician more. Maybe this guy is knowledgeable but the astronaut cred is strictly for show in this context.

I'd say a guy who was a research scientist for MIT's Experimental Astronomy Laboratory, ran the operational part of a satellite communications network and co-founded the B612 non-profit can probably hold his own when it comes to understanding the orbital mechanics involved in nudging asteroids. MIT doesn't hand over master's degrees as participation prizes.
