IPv4 address space is already abused by service providers to "up-sell"
services, there's no reason to think it won't continue with IPv6.
IP addresses are not supposed to be property and addresses are supposed
to be allocated on need. Except if you're an end user, then you have to
step up and
pay for them. e.g Basic Service A comes with 4 ip addresses, Enhanced
Service B comes with 8 but costs $100 more - which makes the consumer
think IP addresses are "assets" or a tangible commodity that the ISP has
the right (or even obligation) to charge for, instead of just some
arbitrary bits that cost almost nothing to administer.
But NAT is not going to disappear unless there's a simple, standard way
to receive or register your own IPv6 prefix.
Maybe you already do - aren't we overlooking 2002::/16? Everyone with
an IPv4 address gets their own /48 already. The RFCs say these can
be used for native IPv6, although the primary use is in 6to4 tunnels.
