> Each citizen can then be assigned an unique IP address

You don't understand how IPv6 works.

The feedback is fair enough given my phrasing. Of course, IPv6 can't give you a fixed IP address everywhere you go; because that's determined by network topology and IP assignment.

All I'm saying is that there's better segregation of the traffic from each IP resulting in easier analysis without the cooperation of NATing layers.

You would want to use NAT with ipv6 if you want to hide somewhat your traffic— say at university as one example.

No you wouldn't. You would use temporary privacy addresses in your SLAAC prefix (this is the default for a few operating systems)

IPv6 prefix is enough for tracking

IPv6 prefix is assigned on a per router basis, you know, like how IPv4 and NAT already works.
