 Speaking as one of those pesky university people (although we don't use
quotas): one of the reasons this happens is that servers are a lot less
expensive than disk space. With disk space you have to factor in the
cost of backups and ongoing maintenance, wheras another server is just N
thousand dollars in one time costs and some rack space.

(This assumes that you are not rack space, heat, or power constrained,
which I think most university environments generally are not.)

 Or to put it another way: disk space is a permanent commitment,
servers are not.
