It's really a question of scale. Would you be as okay with the government's ability to do this if they could flip a switch and suddenly do it for all of a person's mail immediately and without detection? What about making that system available to anyone, irrevocably, who managed to get access to that system at one point? And would you put penalties in place for people who, when their mail is opened, are found to be using a cypher of their own? Is it illegal now to speak in code at all?
