> If you can tolerate encryption without authentication, it is good for you, but no good for me.
You're missing the point there. Which is better: no encryption whatsoever, or encryption without assurance of who you're talking to? The second is plainly better, as it defeats at least *some* types of attackers (those who have intercepted, but do not have the ability to modify your traffic). By now, all web ought to at least be at the "encryption without authentication" level.
Clearly, authentication of who you're talking to is an important feature to have, but requiring that be present to enable the use of encryption at all was a colossal blunder in the development of HTTPS.
