In meatspace we expect the government to use kinetic force to stop people from attacking us. Like if I leave my door unlocked and some person comes in to start stealing my stuff, the cops really will respond and come stop that person (I have had a home breakin they responded quickly to). They didn't blame me for having bad locks. I pay a lot of taxes so my walls and locks don't have to be perfect.
In cyber land, it's an anarchy. The government offers no defense. But there's no reason someone can't offer a deterrent. Like if you knew who broke into your servers, and there was a goon squad that went and broke down their door either kinetically or electronically I think a deterrent strategy could eventually work. Like it literally does for meat-space security.
(Not totally sure I want that, but I'm just saying it would probably work and we haven't really tried it yet.)
