I think lawyers are still the new lawyers. One of the major benefits of society is to remove the need for individuals to keep their own firepower. You're allowed to defend yourself, but the goal is to make it so you can feel safe in a city of 8 million people with no more than a heavy bag, cell phone, or can of mace. In the digital world, you still need self-defense (network protections, strong passwords, small attac…
That doesn't actually work here. If someone attacks you from Russia or China or Nigeria, there are no lawyers that can help you.
The reason hack back is unwise and unnecessary is that you don't need deterrence to prevent cyber attacks. In meatspace anybody with a rock and two hands can steal your television and the defenses necessary to prevent that are significantly more expensive than relying on the state to use prison as a deterrent.
But it's a lot more practical to maintain a secure digital system than a secure physical system, because digital systems fail closed rather than fail open. If you can't pick a physical lock you can still break a window or bust down the door, but the equivalent brute force against digital systems yields only denial of service rather than unauthorized access.
That doesn't mean you can't screw it up. Possible to succeed is not the same as impossible to fail. But it means it's possible to have a good enough defense that you require no offense.
