Not a choice now. If people have physical access to Macs at the moment then it seems to me there are two options right now: either 1) you have changed the root password, hopefully to a strong password or 2) they'll be able to login as root.
Right now you can expect the participants in this thread to be a little smarter than the average computer user.
