Even then, you need a swap partition.

Off the top of my head:

* Because then there's nothing stopping /home from
   spilling over to /tmp, or vice versa.
* 'df' is faster than 'du'.
* If you give each user their own LV as a home directory,
  there's no need to run quotas.
* you can reuse /home/* between multiple OSes
* you can reinstall the base OS without touching /home/*
