> If you already have access to the machine and can create files outside of your home directory, what stops you from causing even greater havoc?
These systems don't let you put files in other people's directories. You can only create things in a specific spot, and if that thing is a directory then you and only you can put files inside it. Sometimes the only thing you can make in that spot is a directory.
(Other users can access those files if you explicitly add them to the permissions, of course.)
