Ask HN: Original implication of IPv6?

I apologize, as this is a fundamental question I got from a school kid (We correspond in a User Group) and it got me into a thought...

The early implication of IPv6 was that everyone/everything would get the power to host their own content and be identifiable over a network. It was touted as a boon to distributed internet people; But it didn't turn out as well. I think the main culprit behind this is the NAT, which kinda serves as a control mechanism. Can we get rid of the NAT??

I answered back by stating the usual "Security and Privacy Reasons", but I think there must be something more to it. Network is not one of my specializations.

What are your thoughts about it? Also Is there an initiative for a distributed Non-NAT network?
