I'm sorry, I just don't get why they are whining that superheroes saving the World is a bad thing.
I guess his anti-superheroes argument could work if he is just referring to isolate accidents that only involve people who are very willing to risk their lives for the thrill and excitement. I can see why those people wouldn't want superheroes to get in their way. But then he goes on bitching about superheroes saving the world from dictators and alien invasions.
"Yay, we sure are lucky that there are no superheroes to prevent wars and disasters from killing and maiming billions! That means we get to live the dream of having cool adventures over the death and suffering of countless innocents!"
