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

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.
