> participants with deeper pockets have an inherent advantage
I do think they have deeper pockets because they are more informed/sophisticated players, so the whole argument is kind of circular.
Not sure if you've seen the price of silver, but those spoons are going for a pretty penny these days.
If I inherit a billion dollars tomorrow, I will have zero additional information and be no more sophisticated than I am today. But I will have deeper pockets than any retail investor and will be able to withstand market irrationality longer than them.
