Hogwash.  NAT vs encapsulation is about equal cost in the CPE device.
You only have to size/distribute the tunnel endpoints on the ISP's
side.  The extra 20 bytes per packet is nothing.

Native is better if only because there is likely to be less configuration.

And can you say that you are ready to turn IPv6 on now?

It isn't IPv4 or IPv6.  It's add IPv6 to the existing network.  You want
to charge for the single IPv4 address most home users get.  There is no
wastage.
