You are right, LaunchAgents/org.freedesktop.dbus-session.plist is meant
to be run by the current user, not root.

And yes, the instructions look kind of wrong. launchctl load -w without
sudo does not work because it requires write access to the file. But if
-w is not used, the Disabled key will not be removed and it cannot be
loaded automatically at system startup time...

dbus does not use the startupitem.* code for
org.freedesktop.dbus-sesstion.plist as it installs multiple plist files
which startupitem.* cannot handle.
