"So you KNOW unbreakable encryption is out there. HOW ON EARTH CAN YOU EXPECT BAD GUYS TO STOP USING IT? Just because you tell them?"
Just detect its use or it's seeming thereof and bust them that way. It may be unbreakable, but it's still not UNDETECTABLE. If there can be a provably unbreakable AND undetectable encryption system that gets released to the public, then civilization as we know it is probably doomed.
"Do you expect to win elections this way?"
Can, will, AND HAVE. You underestimate the stupidity of the average citizen/subject.
"Give it up. You have lost."
No, YOU give up. There aren't enough of you left to matter.
