I disagree.

For single user systems this is often of little import.
For larger systems it is about user control, damage containment,
and administrative ease.

/usr may be a read-only filesystem.

A runaway program may only fill one filesystem.

A small root partition is less likely to be struck by badness.
This seems old-fashioned as drive reliability has improved.  But
when the drive suddenly starts to wobble and uptime shrinks 
dramatically, it may seem a prudent thing to have.

A /tmp partition gives a size to a userland playground and keeps
such play separate.  Some sites with small disk quotas for users
encourage users to use /tmp when they need space for a build or
whatever.

Differing backup needs can be contained in different partitions.  My
/pub partition has stuff that I could get off the internet again,
the backup policy is very slack.  My /local partition is locally
generated stuff and foreign stuff that would be difficult to reimport,
it has a more rigorous backup scheldule.
