Because then:
Use a secure password or key. Security by obscurity is no security.
That is not the point that was made. Once access to sudo or root you already have lost.
You're making it that much easier for someone to brute force logging in or to exploit a known vulnerability. If you have a separate root password (which you should) an attacker needs to get through two passwords to do anything privileged.
This has been considered an accepted best practice for 20+ years and there's little reason not to do it anyways. You shouldn't be running things as root directly regardless.
When you have secure passwords kr key auth. Brute force is not a problem. What vulnerability are you talking about? Complete auth bypass? Then the username would be no problem either since you can just brute force usernames.
Heartbleed was a thing that happened.
Security though obscurity, BY ITSELF, is not security. But it's great at slowing attackers and thwarting automated scripts.
It's bad security to ignore possible mitigations to a problem just because it isn't as full fix.
Defense in depth.
Anyone who's certified NET+ or higher knows this.

Does a great job actually explaining a lot of my points. And it is produced by an actual security auditor and researcher. Just because everyone is doing it does not make it a security benefit that matters.
