WRONG. You clearly don't understand SELinux at all. Try booting in enforcing mode with an empty policy file (well, not quite empty, there are a few mandatory labels you have to create before it's a valid policy file). /sbin/init will load the initial policy, attempt to re-exec() itself... and promptly grind to a halt. End-of-story.
Typical "targetted" policies leave all user logins as unrestricted, adding security for daemons but not getting in the way of users who would otherwise turn SELinux off. On the other hand, a targeted policy has a "trusted" type for user logins which is explicitly allowed access to everything.
That said, if you actually want your system to *work* with any default-deny policy then you have to describe EVERYTHING anyways. How exactly do you expect AppArmor to "work" if you don't allow users to run "/bin/passwd", for example.
