Quoting Asa Zernik:
Just saying, it's not like Ubuntu is any more dependent on sudo than any other *X system.

Well by default the root user (UID 0) has no password set and is as such effectively disabled ("passwd -l root"). Sure you can "sudo su" or "sudo -s" but that is a function of sudo and nothing else. Logging in as root via a virtual console is, by default, not possible. So yes, Ubuntu depends exclusively on sudo if you haven't every set up the root user by doing "passwd root".
