The power of linux/unix. It allows you to do anything you want to the
system as superuser, even if it isn't too wise an action. That's the
prime reason one shouldn't stay logged-in as root all of time and chance
compromising the system or accidentally issuing unwise commands.
Such as the one I did early on: chmod -R o-x /
As for being read-only and unable to modify easily, can't really give a
definitive answer to the. I presume (wrongly, most likely) that it's
to keep one from doing even more damage inadvertantly by requiring some
forethought to be applied before acting.
