It's a modestly interesting point, but it certainly doesn't make sense in the concept of pizza. The author tries to appeal to fairness, but where the fallback positions are knowingly arranged randomly. Therefore, the naive 6-6 solution is just refusing to adjust for a superior random arrangement in the experiment, which was unfairly assigned. Therefore, I would expect the naive 6-6 to be chosen the plurality of them time.
There's also a question of if there is any value to clam pizza beyond the initial four slices. That sounds like a lot of food that reheats poorly.
Now, if you want to say this applies to something in the real world as a concept, I would say it's not a novel concept. No one expects a new employee to capture 100% of the value they add, nor do people expect the new employee to work for free.
