No, its not at all like saying that. Its like saying that residential phone users don't need a globally unique circuit facilities assignment (CFA) number.
They do if you want them to be able to receive phone calls from anybody else in the world without requiring the call to be switched through intermediaries with overlapping address scope.
Decentralising the business of call switching to the edge is surely the attractive aspect of voip. If you require calls to be switched through third parties, you're just reinventing the PSTN and all its attendant baggage using a different transport, and there's nothing particularly innovative or disruptive in that.
