Supervisor would perhaps be used to describe that initial state but even that is stretching.

(If anything my example have the actual user as superuser as he/she is the one that can give rights to others)
Since you are linking to Wikipedia, i take it you accept its authority on these things, so i'll quote the article on "superuser":
In Unix-like computer OSes, root is the conventional name of the user who has all rights or permissions (to all files and programs) in all modes (single- or multi-user).

The first process bootstrapped in a Unix-like system, usually called init, runs with root privileges. It spawns all other processes directly or indirectly, which inherit their parents' privileges. Only a process running as root is allowed to change its user ID to that of another user; once it's done so, there is no way back.

It is you that applies the term user to anything that have privileges.

It is you that claims a system with several privileged entities is a multi-user system.
No... everyone else in this thread is trying to tell you this.

A "user" as far as the operating system design is concerned, is a set of privileges. Whether these sets of privileges are actually used by human beings or not is neither here nor there, a computer doesn't even know what a human being is.

Hence the confusion. Because in the real, outside world we think of a user as a human being. But there are not any human beings in an operating system.

Here is a list of some "users" currently running processes on my Linux PC, that are not human beings:
