You are missing both Schneier's point and mine. The point is that if you can contrive of a way to (perhaps inconveniently) pre-share static keys, you should consider doing that instead of relying on number theory to protect your secrets.

No I got that just fine. As you know, I'm suggesting that not using public-key crypto or something else for the same purpose is impractical.

Nerdnit, but it's not like AES is based on some wholesome certified organic granola theory to the exclusion of number theory. Number theory didn't wait around 2+ millennia to be useful only to be dissed like that, man!

and you are conveniently missing his point. If we were to throw away public key technology today and say 'Only pre-shared keys' some significant portion of the internet would simply be unencrypted. What do we do about that?
