I use privacy addresses even while I am at home. Yes, a /64 identifies my house, it doesn't identify all of the people in it.

If they see two IPs on the same /64, all they can assume is some form of weak correlation. Correlating "stable privacy addresses" (cf agwa comment) is trivial. How many network do we use in a day? Home, office, mobile provider, perhaps a couple more. Chances are that advertisers will see you using the same cookie across multiple networks and if your IPv6 address is persistent then you can bet that within a week all your stable IPv6 will be mapped to your profile. It only takes one observation to establish the link and then it is a static link. Ideally you would like your /64 to be renewed regularly (it's not a bad idea to reboot the modem from time to time anyway) and to have randomized IPv6 addresses.
