I'm thinking more in terms of consumer networks. I really don't want my ISP to know exactly which devices I'm using or how many, nor do I want to have every web site be able to track them by globally routable IPv6 address everywhere I go. Simply blocking incoming connections doesn't solve that. Taking credit for someone else's work is not a useful analogy for NAT, nor are the corresponding moral implications relevant. |

So, you would rather use one address for everything, making it easy as pie to track you? You can pretty much pick IPv6 addresses at random (under your router prefix), and you have (many many many) more addresses than the whole IPv4 address space to choose from (it's a 128 bit address space and providers typically give a /48, /56, or /64 prefix at worst... that's 128-64=64 bits... that's 2^63.9999... more addresses than IPv4). In short, you don't really "map" the IPv6 space the same way you do the IPv4 space.
Taking credit for someone else's work very much is a useful analogy: if I can only speak through a third party, and I need that third party's permission to speak, let alone be spoken to, I quickly resent him or her. This is quite the case with current NAT solutions, with system administrators restricting "their" networks, making communication difficult for everyone else (by holding the only globally-routable address or "allocating" only a few; everyone else is second-class).
