Because it is useful to be able to log in as root in single user mode.
It is generally only used for admin/repair purposes, and not for every
day work.

Because you haven't told the system to ask for a password.  In
/etc/ttys, change:

console none                            unknown off secure

to:

console none                            unknown off insecure

Next time you enter single user mode, you will be prompted for the root
password.

You can test it by running `shutdown now'.
