I think that is the perception. I usually hear the defacto answer is drive two rods if that is your only electrode. Florida pretty much makes the Ufer mandatory in new construction since the Ufer inspection is part of the footer inspection so it will always be "available". If you lose that connection you will be chipping concrete in most jurisdictions. That is why the "7 iron" is so popular. There is no exposed copper to be broken off and/or stolen.
We don't see many rods any more in my area but the rules here are 2 - 10 foot rods 3 meters apart. There is so much rock and hardpan clay that ground plates are the rule except for a counterpoise ground for a HV service. We dropped the resistance requirement from our code a long time ago. Given the role a Ground wire serves I think it is mostly all overkill. It is rare that high voltages including lightning ever get on the low voltage wires, the neutral is the real fault current path to the source anyway.
The function of the ground is not to clear faults, it is to create a local ground reference so the case of your drill is at the same potential as the concrete slab you are sitting on. In that regard, the ufer is your best bet. Earth ends up being a significant return path for neutral current tho, in spite of the theory and 250.6. Wye distribution pretty much assures it. Even with delta distribution, you will still be sharing the earth with the neutral. You want a local ground reference.
That term came from here. It is when you turn up a piece of rebar, built into the wall and make the Ufer connection there. That is very popular here in SW Florida but right across the swamp on the East Coast, AHJs don't like it.
As to the '2 rods'...basically most ECs I know 'just do it', as if it's looked at in a dollars and sense standpoint. Taking into account the $$$ of testing equipment, driving the reference rods & performing the test, economical sense is to drive the second rod & the job is done.
For some time, quite a few guys still installed rods with Ufers, and I still find the occasional 'water ground' with a jumper on the 2" plastic main, and PEX piped resi.
