Agreed. I'm not even sure if it's all that interesting that encryption plays a role: I think privacy, and by extension secrecy plays a role. And in our world, cryptography is increasingly a precursor to both privacy and secrecy.

But I think the fight about making cryptography available, really is the fight for right to privacy, and even right to secrecy in certain areas of our society. The USA is fortunate in some ways because of the constitution, and its repercussions throughout modern history - even if law enforcement can build or buy a device to see through walls, that doesn't allow such tools to be used without regulation.

But now is the time to regulate large scale meta-data, traffic analysis, in addition to guaranteeing a right to technology that allows data to be kept secret.
