A couple of things. Grounding (hooking up to a grounding electrode)
is really not so much a matter of human safety as it is to provide a
path for lightning and a way to equalize voltages.

Please calculate the the cross-sectional area of a conductor required
to carry the current from a lightning strike, and compare and contrast
that with the typical #12AWG cross-sectional area.

Grounding an electrical system will not provide a path for lightning.

of course it does. lightning wants to find a path to ground. it will
either do it through your home or you can provide it a way to get to
ground easier. the idea is to make it easier for lightning to go to
earth through the ground rod rather then through your house to earth.
