Maybe this is just me nitpicking, but as long as you limit your randomization process to a pool of allowed actions, you’re still largely predictable insofar as you predictably choose from within that pool of actions. For example, if you’re randomizing your actions on a digital market, you’re maybe deciding whether to buy or sell or hold or whatever, but you’re probably not considering a DDoS attack on the market etc. Or, even a human who tries to randomize their actions can’t randomly decide not to breathe so as to thwart their predictive adversary. And so on.
