Why doesn't Sony just open more Naughty Dog studios and close all non-Naugty Dog ones?

Because most of Sony's studios don't have the talent that Naughty Dog has.

They may not be on Naugthy Dog's level but Sony has some of the best and most diverse Studios: Media Molecule, Sucker Punch, Santa Monica, Polyphony...etc
