Your logic here is flawed. It's entirely possible that they would first attempt to do the right
thing and request a shared block through the policy process falling back to these requests
while they are still possible, but, after exhausting the policy option.

You criticize them from bringing a study that is not ARIN-specific to the ARIN region
for what is a global issue, but, they tried to address this globally and it failed to
achieve resolution.
