There's a subtle but significant difference between what cookies give you,
which is "This is the same entity that visited our page at 7:48PM last
Tuesday", and what easily trackable IP addresses give you, which is "This is an
entity located at 1948 Durhof Street".

Yes, it's often possible to to map between one and the other - but anonymous
and pseudonymous are two different things.  It's quite reasonable for somebody
to want to be one but not the other - though it can be difficult in practice.
It's even quite reasonable for somebody to wish to be positively identified,
but their location not easily determined - for instance, I'm posting this as
myself, but I may wish where I'm posting *from* to remain a secret (for
instance, if my location reveals I'm not at home and thus burgling my residence
is more feasible).
