Jon isn't that bullet proof. That preview is more evocative of goldenage outlaw superman who couldn't handle more than a bursting shell. Moreover, superman wears the s for a reason. Originally it was to piss off police officers and corrupt politicians. It's a freaking police badge. So, naturally it draws attention.

I believe, an ultraboy and ultraman wouldn't be an authoritarian. He would be more an absolute anarchist smashing everything and anything, burning everything down to the ground especially technology like the monkey king sun wukong and hanuman before the curse.

There is also possibility of a superman becoming totalitarian like darkseid as well.
