I agree that autoconf is desirable. Now, please explain to me why it is desirable for the address to change at random intervals from the customer perspective? (i.e. why would one want dynamic rather than static auto configuration?)

Because IPv6 was originally designed with the goal of completely transparent renumbering. Indeed, after many WG meetings over many years debating renumbering and all the problems that entailed for IPv4, some of my drafts proposed that IANA would renumber IPv6 for every ISP and IX at regular intervals! Thus, enforcing that all the dynamic configuration protocols actually work. :-) And nobody starts issuing licenses based on IP addresses anymore. :-(
