I keep thinking that if encryption was an actual weapon, and keys actual ammunitions¹, they would be much easier to defend than they actually are. Funny that: cryptography is relatively harmless, making it all the more immoral to restrict it. But that same harmlessness make it that much harder to defend. I mean, just try to take away nukes from a nuclear capable nation, or guns from a Texan village. Maybe you can, but the costs of doing so tend to give pause.
