The difference between NIRs and CIRs is that NIRs are still required to
follow the policies developed by their parent RIR, whereas CIRs could in
theory do anything they want, e.g. giving PI addresses to any entity
that pays some nominal fee.  The resulting explosion of prefixes in the
DFZ from such a policy could cause a global meltdown.  More likely, it
would cause ISPs to filter the CIR blocks to protect themselves, which
would almost certainly result in government regulations that ISPs must
accept routes from the relevant CIR, which could in turn cause
country-specific meltdowns.  Worse, some governments might use the
availability of CIR blocks to ban the use of RIR/NIR blocks.  The end
result: the current global reachability (except to Verizon) that
everyone with RIR/NIR blocks enjoys today would not be available in the
future--something that many governments (and thus the ITU) want to
happen anyway but is undoubtedly bad for consumers, bad for the entire
industry, and bad for freedom (as in beer) globally.
