Unless I become Robert Johansson[0], my imagination and capacity for material engineering is not going to be enough to simultaneously have a life and protect against a single sufficiently motivated individual, let alone a nation state putting a lawful (by its standards) order against me.

I’m only even safe from nutcases because the nation collectively has enough experience dealing with people who think they know better.
