SUdo is useful even when you do have root. I use it all the time

know you can use "su -c bla bla" but sudo is quicker and easier to
remember.
I, OTOH, find su -c quite satisfactory, TYVM. The only reason I have
sudo installed is that there are some install scripts that use it. Of
course, back when I first started using Linux at home, almost 20 years
ago, RedHat didn't come with sudo so I never got in the habit of using
it. I knew about it because I had to telnet to various Unix/Linux
servers (all inside the corporate firewall) at work, and worked with
shell scripts that used sudo, but that's it.
And, as far as security goes, all you need to do is disable Telnet and
configure ssh to disallow direct root login. That way, even if somebody
manages to crack your password and get shell access via ssh, they can't
use sudo to do any major damage. (I'm never in wheel, and my username
isn't in /etc/sudoers, just to be safe.) Paranoid? Not really, it's
just that I see no reason to have sudo set up if I'm not using it.
