Because with CGN, DS-Lite and NAT64 you have a third class IPv4 internet. You can't run any services what so ever. You cannot do anything that requires anything other than UDP or TCP over IPv4. Try running IPv4 in IPv4 or IPv6 in IPv4 tunnels over CGN, DS-Lite and NAT64. They do not work due to the addresses sharing. Try running a NAS from behind them, it does not work. With one level of NAT that you control (second class internet) you can kludge around some of the issues cause by not having global addresses ability of every machine. UPNP helps here. As for you ID sticking out, IPv6 is no worse that IPv4 is for all practical purposes with currently shipping IPv6 stacks. They have privacy addresses and they are turned on by default. Now with IPv6 you have a choice of whether to offer a service or not and you don't have configure port forwarding etc. You can have both stable and temporary addresses at the same time for the same box. You can choose which to use on a service and/or role basis. But hey a third class internet is "good enough" for the plebes at home. They don't deserve to be able to run servers from home. They don't deserve to have a first class internet.
