I mean I already knew something was weird when I couldnt su into root and do... root things without a bios hack on a Mac. Thats just not how Unix works at all... The whole concept of root is you are root no exceptions.

SELinux doesn’t let root just do whatever it wants.

It's typically not enabled by default though, but I suppose that's a fair point.

That very much depends on what distribution you use. The Fedora/CentOS/RHEL world has had SELinux enabled by default for years. The Debian world has not but AppArmor is pretty popular there and while that's a fairly different system it hits many of the same sandboxing points. Beyond the default configuration, anyone who is following a hardening standard like CIS is going to have SELinux enabled, too.
