Unlocking implies that there's a lock. When you have services like gnome-keyring storing your passwords, you don't automatically unlock them even though the files and the contents inside are owned by your user. You still need a security mechanism to ensure that not just anyone is accessing your resources. We already do this in several ways with the login screen before or after login, including A) what you know (password) B) what you have (smart card) C) what you are (biometrics such as fingerprint)
