> No sane person believes that there aren't really nasty, organized criminals in the world, and no sane person believes that said criminals have a right to absolute privacy, including e.g. (the moral equivalent of) search warrants.

That's just a strawman.

Plenty of sane people believe that the threat of criminals doesn't outweigh the threat to individual liberty posed by the state. Additionally, plenty of sane people wouldn't support a ban on locks and safes because it makes it harder to search criminals.

I'm pretty sure I have my sanity in check, and I don't think there's any reason for the government to require private enterprise to break encryption to ease prosecution. It should be hard or impossible for governments to spy on their citizens.
