Depends on what the dynamics of his design are.  I.e. if he frequently
creates and deletes "people", then he can consume a lot of "id-space"
even though there aren't many real people in the database itself.

Personally, I doubt this is the case.  But, can see other applications
where this could be true.  Since you can't reuse old id's, it's easier
to just use a bigger size datum than having to worry how the database
will react when/if you run out of them!
