I think I am in agreement with you, just putting a little emphasis on a couple things that can be taken too loosely.

The GFCI thing - yes it won't trip on first fault, but you need to understand it's intention which is to protect people from shock hazards. That first fault isn't much of a shock hazard, it simply makes a ground reference and the system is now grounded, though unintentionally.
