What if I'm looking for John Smith  and don't know his person-id?  Or
whether it is Smythe or Smyth...  or Jon, or Jan ... or which office
he works in?   A centralized name disambiguation and forwarding
service would come in very handy.

Or, consider those acm.org forwarding addresses many of us use ... why
not expose the actual email address?    I suspect a) we don't want to
expose the real address to slimeball spammers, b) we want to be able
to keep the same logical address if one changes "implementation
details" such as employer, ISP, etc. c) we want a centralized point of
management (at acm.org) for this and other personal metadata we choose
to make public. Similar  reasons apply to the address example.

*if* your users do far more read operations than create/update/delete
operations, and there is a high probability that a document that is
retrieved once will be requested again soon..  Very true on the Web. 
Not true for data enty applications.  Nightmarishly difficult in the
distributed read/write case.
