One scenario is business customers I maintain. They are almost all on my 
network, and I have servers I maintain/admin 400 km away that are not 
mine. When I am logged there, or on-site, I often need to pull some data 
from my main server. Sometimes FTP is enough, but sometimes I need to 
use SFTP or SCP to access sensitive scripts, or to login (when I am 
on-site on far away network).

How do you propose that I use key only auth? to copy my sensitive key 
onto their system? Or is it better to in that case just use password 
auth? I avoid using my passwords on infected systems, or without proper 
protection, but on safe systems it is better to use passwords then keys.

And of course, I have a brother with root access that does not own a 
laptop. And if I even tried to force him to use keys for every 
connection, I would have blue eye in matter of days ;-)
