SUdo is useful even when you do have root. I use it all the time because I don't like actually logging in as root if I can avoid it. I 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.
