You use sudo because you can then revoke access to individual admins. If
everyone knows the root password, the only way to revoke access is to
change the root password. Then you have to inform all the other admins.

And if the root password is leaked? How do you know who leaked it? Who
do you fire? You may never know.

With sudo, you'll know who's password was leaked or cracked.

A multiple admin scenario is exactly why sudo exists.

How many admins are you expecting here? The more admins you have, the
more sudo becomes preferable due to the above problem.

Wait, which one is that? Traditional unix's all-or-nothing approach to security is probably its biggest design flaw. (Hence why SELinux exists.)
