This in turn hurts the purchasing power, which means that completely cornering the market is bad for the actor who does it. This suggests that there's another critical parameter needed for your model.
I did mention the negative feedback, as well as negative feedback on the negative feedback, but yes, you're absolutely right; it's hardly monotonic. And I think my proposed Highlander Constant is not a constant, it's a Highlander Function.
It's only bad for the actor if the actor cares over the timescale of instability, as well. It is an old maxim that the only thing bad for traders is stability.
I'm going to hit a related point in another post.
