I was not referring to the security mechanism of using email for authentication, your
comparison there is correct email is similar. But I was talking about the HA part for which
email authentication is not equivalent! If you temporarily lose access to your email you are
still able to login to your accounts without it, you simply have lost the ability to "reset"
your accounts. With openid if you temporarily lose access to your openid server, you are SOL.
This really is different.

Many people today have a single point of failure: the local passwords list file.

These people still have at their disposal simple cheap HA solutions to this if they choose.
1) memory
2) cp passwdfile passwdfile.bak
3) + email passwdfile.bak file to offsite email account
4) + encrypt passwdfile.bak before emailing offsite
5) cp passwdfile to USBstick/passwdfile.bak
... the list goes on.
While not everyone chooses to do these, at least they are reasonably available to them.
