Just because the address space is mind-alteringly larger does not mean the  
same flawed thought process isn't being used.  In the mid-80's, /8's were  
handed out like candy because there were "lots of address space" and  
"we'll never use it all."  Well, that didn't last very long.  I've  
listened to IPv6 advocates singing that same song for a decade.  They are  
doomed to repeat the same mistake. (sure, it'll take longer than with  
IPv4.)

IPv6 was designed to "not need DHCP."  DHCPv6 has come about since people  
need more than just an address from "autoconfiguration".

I can recall many posts over the years from the IPng WG telling people  
they didn't need DHCP.
