On the plus side, this (staying with IPv4 behind NAT behind NAT...) will further instil the idea that an IP address is not a person. As soon as governments/corporations loose the ability to track/sue individual people, they'll be all over IPv6.
They aren't the same thing, but that doesn't prevent them from having features in common. They are both big, powerful entities that don't have my interests at heart, and are both therefore threats to my liberty (especially when they work together to undermine it).
Nice try at a silver lining tho. :)
