How did we arrive at networking? I feel like we are on two completely different pages.

I was talking about your regular end user machines, what we usually call “desktop computers”. They are connected to the internet, but I don’t have any way to remotely login into those. And I have a single person per computer. There is no need to disable root passwords on these, seeing that Larry executed a command as root won’t provide any insight, I know that Larry is the only person who uses the machine. And it can complicate things in a sense that if Larry fatfingers his password three times and gets locked out, I’ll have to get into his filesystem somehow and remove tallies manually instead of just logging in as root and doing faillock --reset.
