Electrodes are not intended or expected to trip a breaker
Say what!!! You don't use temp cables and extension cords with EGC's?
Helps to stabilize system voltage, prevent potentially destructive surges to equipment, reduces possible step voltage potential during untripped shorts...
The real question is how do two rod electrodes make the installation any less safe? And of course the answer is, they don't.

Yes but tripping breakers is not the job of groundrods or water lines or concrete encased electrodes.
The fault path during a ground fault is via the equipment grounding conductor through the neutral to ground bond at the service panel.

As Bob stated you only really need to main bonding jumper to ensure that when current travels on an EGC it will open the OCPD. Ground rods have a completely different purpose as Smart mentioned.

The code would permit a 1000 amp service to have only two ground rods as the grounding electrode system for the service. What is that you think the ground rods do to make the service safe?

The ground rods or any grounding electrode has little to do with opening of an OCPD. The connection of the EGC directly to the neutral will take care of that.
