I think this is an accurate assessment but I think authentication and account management should be seen as separate from 'identity'. Authentication can be useful without being associated with a real-world identity; for example, it can be useful for spam-prevention as an alternative to signups with captcha. You could theoretically log into multiple services which you don't trust by signing messages using your private key without revealing your passphrase to any of those services.
