You guys aren't *near* paranoid enough.  :-)

If the ISP 

a) Assigns dynamic addresses to customers, and
b) changes those IPs on a relatively short scale (days)

then 

c) outside parties *who are not the ISP or an LEO* will have a 
relatively harder time tying together two visits solely by the IP 
address.

While this isn't "privacy", per se, that "making harder" is at least
somewhat useful to a client in reducing the odds that such non-ISP/LEO
parties will be unable to tie their visits, assuming they've controlled
the items they *can* control (cookies, flash cookies, etc).

Imperfect security != no security, *as long as you know where the holes are*.
