Using Linux or OSX on a modern single user computer, the separation between root and non-root makes very little sense. I don't care if I "rm -Rf /bin" because I can reinstall all of it in less than an hour. It's an inconvenience, but hardly the end of the world. On the other hand, "rm $HOME/*" would be a huge pain in the ass, potentially losing personal data that I can't just "apt-get install _____" back. It does make sense for shared computers, but not many people running OSX and desktop Linux are running on shared computers.
