And also, let's not forget that IP nets are not used exclusively for consumer oriented appliances. In addition to enterprise nets, which have different criteria from private users over ISPs, there are control system networks. On factory floors, in all manner of vehicles, and so on. Networks running machinery, providing navigation data, and on and on.

Privacy of an individual user, or of an individual host, is exactly what these networks cannot allow. So no, I don't see a future in which there are no stable addresses.
