"With a physical safe, at least it's possible to prove that I don't have the key in my possession." Immediate, on the person, maybe. But you cant prove you cant get hold of it. That's the old proving a negative thing. In fact, even if they search you, all it proves is that they didn't find it, not that you don't have it. When governments start expecting us to prove we didn't do or don't have something, you might as well give up. Its a line no one should be able to cross, not least governments.
