Everything Anton has said makes perfect sense; there is nothing "strange" about it: you cannot cleanly and safely shut down the system unless you first gain root privileges. What is so difficult about that to understand?
And there are many ways of gaining root priviledge! Some implicitly configured, some you may need to configure. There's a number of things relating to, for example, burning DVDs, where I have set up access to the DVD device, even though it is nominally owned by root. There are a few other commands that I've configured into /etc/sudoers so i don't need a password each time. None of this is odd; administrative delegation of specific funtions goes back a long way. There a paper from USENIX/LISA-IV 1990 titled "Life without root" on delegating what would normally be root-restricted subsystems to ordinary or to specific users. That was a long time before SUN came up with PAM and RBAC for the same thing.
