Your identity is your private key. It can't be taken away in a way how your Google account can be just disabled one day. We also have a way to retain control if your private key gets compromised - you can have a parent key, which can then be used to disable your compromised key and re-assign your name to another key. Since you never use your parent key (presumably kept in a safe offline place), it gives you some degree of protection.
