If the Fortune 1000 and critical infrastructure providers cannot obtain
direct IPv6 allocations from a numbering authority, and refuse to get
IPv6 from their ISP, then if there are enough of these people running around
I am sure someone will design a network address translator that uses
the IPv6 site local addresses, and you will have the same exact situation
as what exists right now with IPv4.

If you think that you have a better way to balance the needs of the Internet
community to not have a gigantic route table with an org or business DESIRE
to not get allocations from their ISP, then let's hear it.  And keep in
mind that the need of the Internet community is a -requirement- the desire
of the business community is a -wish-.  The Internet cannot survive with
every single org advertising their own route - it cannot survive that way
today under IPv4, and it won't be able to do it in the future under IPv6.


PS  Some out there regard the existence of NAT as a tragic failure of the
IPv4 Internet, seriously limiting it's use. ;-)
