Toy example and non agentic real life examples don’t have the coupling/symbiosis of walls siphoning work from balls to maintain the walls. Walls might be built from restricting the dimensions along which the ball tends to move/look ahead so that it treats saddle points instead as cul de sacs. Lowering momentum/energy in general to make the walls you need to build not as high.
