Because typically you only allow root login via console or an existing 
login.

You can brute force a user password (or sniff if the admin is lazy in 
how they connect - IE not using proper pass phrase, MITM attacks - 
possible with the SSH bug that Debian/Ubuntu had) etc. but normally the 
root account is disabled from remote login so it can't be remotely brute 
forced or sniffed.

What you normally do is give sudo access to the commands (or wrappers to 
the commands) that a particular sysadmin might need to use but you don't 
give them full root access, thereby limiting the damage that can be done 
should their password be compromised.
