So you think it would have been a better lesson if he had crashed at 180 mph and probably have died? Better lesson for who? His family? 
I can't speak for "DC Concours". But I can say that I understand the sentiment- this guy is likely to end up injuring or killing someone else. If it came down to it, I would rather him die and the threat to us all be over than someone innocent to die due to his extraordinary recklessness and disregard for everyone. Of course, in such a case, there is no lesson to the perp who died, can't learn anything when you are dead.
On the way home just last night, I saw a driver 1/3 mile ahead slam on the brakes and STOP in the middle of the right lane on 64 (with traffic going 65MPH) because he decided he didn't want to miss an exit ramp. He then made a sharp 90 degree turn across solid lines to get the ramp. A week earlier I saw another driver BACK DOWN AN EXIT RAMP because it was the wrong ramp for him! These people seem to care nothing about the safety of others. Instead of just going to the next ramp, they somehow decide that the instant "correction" of their own mistake and subsequent inconvenience is worth such extremely dangerous behavior.
I have been driving a long time, it could be my observations are skewed somehow, but it seems like every year, I see an increasing amount of such insane behavior, as if driving is were video game.
