Re: People do not want it
If you don't want your light bulbs on the same network as PC and printer then you should be screaming for IPv6 and "network coloring" (think automatic sub-net), not making a case against IPv6.
And IPv6 is not too complicated - the vast majority of home users will not have to do anything at all if carriers provide properly configured CPE. In some respects it can appear more complicated (SLAAC can appear scary to people), but in others it is less complicated (no NAT).
