We are talking Internet operations, not Internet politics.
You are right as far as that goes but it is ARIN et al. who
hand out ASNums and IP addresses to the network operators 
who actually *USE* these numbers in operational networks.
People don't care where the numbers came from, they care
who actually got the rights to use them, and then what
those orgs did with the rights, i.e. an IP addr block owner
may delegate the rights to announce a subset of their space
to a specific ASnum holder.
