ARIN does not provide transit - how could they guarantee or even just 
provide best-effort routability?

Perhaps, but that is misguided.  ARIN, et.al. don't get involved in 
peering or block lists or firewall configuration guides or hurricane 
forecasting or ... anything else that bars reachability.  If I decide 
to unilaterally block traffic from your address range, ARIN, et.al., 
can't do anything about it.
