IP6 doesn't need NAT. NAT is only used because of the shortage of IP4
addresses. And yes , all PCs do send packets with a public IP
address , but the point is with IP4 that address changes and its
impossible to identify which actual machine they came from - the best
you could do with home broadband would be the house itself. With IP6
you can identify the actual machine - and that goes for when you're
supposedly using "anonymous" public wifi. So if you have a laptop your
movements could be tracked from every time you connect to a wifi node
or an ethernet cable. Paranoia? Perhaps , but eventually anything that
can be abused by someone will be.
