...uhm, and? What is the real difference with a IPv4 address and
privacy?


The difference is that someone using a dynamic IP address is still
recognizable by the lower 64 bits of their dynamic address because this
part is always the same. (But cookies do the same thing.)




What is interesting is that people can identify a EUI-64 unicast
address no matter where you are. For example, i use my laptop at work
and at home (assuming I had an ipv6 connection at home). I could be
identified as the same computer, without using cookies, since my base
64 address would be the same, despite the network prefix.
