The GNex has some other type of tempered glass (DragonTail?). It was softer than Gorilla Glass, and made it more susceptible to scratching but a little bit less prone to smashing. I never use a case or screen protector on any of my phones and the Galaxy Nexus was the only one to ever get scratches that you could see and feel (Everything else has little micro-scratches that can only be seen at specific angles). The GNex was the only phone I've dropped too, and it was on concrete right at the corner too. The screen was fine but the plastic body had to be replaced ($20, good as new).
So yeah, Gorilla Glass is fine without a protector, unless you mistreat your device.
