The concept of randomness being a placebo for agency still just doesn't make sense to me. Output randomness diminishes your impact on what happens to the system. Does that mean it's a placebo for agency? No. It just means that you have less agency in the game's outcome when you have output randomness. The word "placebo" makes it sound like you're being cheated out of agency you're supposed to have. That's simply not the case. There is no expectation of perfect agency when people play colloquial games. It's totally unlike the expectations people have when they are given a pill that they are told should cure or help against some illness. It's more like taking a pill someone gave to you randomly and then being upset that it doesn't heal your broken arm.
