Why?  There were no policies to restrict how address space was transferred (or anything else) when they got their space.

When most of the legacy space was handed out, there were no restrictions on what you could do/not do with address space simply because no one considered it necessary.  Much later, a policy regime was established that explicitly limits rights and you seem surprised when the legacy holders aren't all that interested.

Hah. I suspect you misunderstand.

I suppose it depends on your definition of "working".  

I've been told there are entire countries that operate behind multi-later NAT (primarily because the regulatory regime required ISPs obtain addresses from the PTT and the PTT would only hand out a couple of IP addresses).

I have put wireless gateways on NAT'd hotel networks and it works for client services, for some value of the variable "works".

The problem is, anecdotal evidence isn't particularly convincing to folks who are trying to decide whether to fire folks so they'll have money to spend on upgrading their systems to support IPv6.
