Your response is a non sequiter. He said that A implies B. You replied that
would be a major change because we have always felt that C was also true.
However, there is no inconsistency between B and C. In fact, C is
independent of B.

Perhaps you took his "A implies only B" to mean that he was claiming your
particular superset of B was false. But he did no such thing. He simply said
it wasn't implied by A. However, that takes no position on its truth or

In this case:

A = A market for address space
B = Ownership of a right to use address space only on the Internet
C = Assignment includes right to use address space in non-Internet contexts

In case it's not clear, he argued that a market in address space implies
that you can own the right to use address space in the limited context of
the IPv4 Internet (A implies or requires just B). He said nothing about use
of address space in any other context. He didn't say you couldn't get it or
didn't have it, he just said that only ownership of a right to use in the
limited context of the Internet is required for a market in address space.

And, in fact, when someone wants to "buy IP addresses", what they want is
the exclusive right to use those IP addresses on the public Internet. If
this right can be had and transferred, then there can be a market in address
