I'm ready to switch passwords for anything else as long as:
1 - It can't be extracted from me by an easier method than torture or blackmail.
2 - It stops working forever if I'm dead.
Agreed. Other authentication factors can be taken from you without much difficulty, but password access requires actual conscious cooperation.
On the other hand, I know where they're coming from. For the last five years I've been working on getting as many network services as possible to work with Kerberos authentication. So far, I've got OpenLDAP, OpenAFS, Netatalk (AFP), NFS, OpenSSH, Exim (SMTP), Dovecot (IMAP) and Apache (HTTP) to work with it, which has eliminated a lot of password use, as well as improved security. It would be fun to add MFA to the equation, but I'd still prefer to somehow remain consciously involved in the authentication process. Finally, people may hate having to remember new passwords all the time, although they get used to it, but the fact that they are so easy to change is also an advantage.
