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.
