However space is not the only reason: Back in the times of non-journaling filesystems (and slow disks where a fsck could take 40 minutes or more) it was highly desirable to have a small root filesystem that could be checked quickly, to root had the chance to become active.
Even today when something bad happens, one would probably prefer to have multiple smaller filesystems to repair rather than one "huge pot". MHO.
Agreed Windows users who only know C: never wasted much thoughts on structure; see the mess in C:\Windows. But I thought UNIX was highly structured...
