[DA] I agree, I hear it is tough to keep a hold of a genie. While prop 136
does not deal directly with address markets, how markets develop would be
a direct consequence of prop 136. If 136 were abandoned, transfers from
one to another can still occur under existing policies. What you are
proposing here is the difference between an unrestricted market that this
proposal could enable, and an attempt at evolving a structured market that
we hope could limit abuse under existing policies. I'm not naïve enough to
think that existing policy couldn't be abused, but I cannot see how 136
could provide an environment with fewer negative consequences.

[DA] I should also revise an earlier point I made that brokers would be
the only beneficiaries. This change is not limited to brokers facilitating
the exchange of /24's or /16's between individuals or companies. This
proposal could open the door for governments or international
organizations to acquire /8's and circumvent the RIR's. I think the
potential of these implications far outweigh the desires that a legacy
resource holder may have to avoid ARIN policy.

[DA] I don't see a way around this problem. If a holder X has a non-(L)RSA
resource and opts out of ARIN provided services, you suggest ARIN would
provide a pointer to holder X. Now holder X transfers to holder Y. Holder
Y has no obligations whatsoever to provide WHOIS services or pointers.
While holder X may have a pointer, which they are not obligated to do, it
will likely be irrelevant since holder Y, or anyone further down the chain
has no obligation to do anything. This makes WHOIS services far worse then
they are today.
