You are in an environment that requires thought, training and equipment to survive.
Eliminating a possible risk is all the basis in reality you should need.
Actually, it's about balancing risks. There is your fantasy-land risk of choking on your bungie necklace, and then there's the real world risk of having to locate and use your alternate, possibly while your hands are otherwise occupied. I know which one of these I would choose. Given your reference to thought and training, I'm sure you realize that training for diving in risky environments like caves and wrecks universally includes using an alternate on a bungie necklace.
You can defend your point of view till you're blue in the face, but reality still will not support it. Thousands and thousands of technical dives in a gear configuration that has become standard, and never a single case of what you say is a "hazard."
