One of the benefits of the 16 byte address was to remove the dependence on hierarchy.  With the 4 byte address there is partitioning of the address between countries, RIRs, service providers, companies, networks, sites, and finally resolving to a node.  By adding to the address space it allows for "mobile" ip addresses.  The same ip address at work also works at home regardless of who or what the ISP is.
