You need a root password to ssh into and reboot a remote machine that stopped accepting logins from normal users (stuck NFS, stuck NIS, out of memory, dead user home directory disk, borked pam, etc).
Definition of remote machine? Not under your desk; takes longer than 5 minutes to walk to a different building to press the reset button; it's at CERN and you have to send an email to somebody to go find it and press the reset button. etc. Why not "login as normal user and sudo into root?", see above, machine is borked and does not accept login from normal user.
