It's not about talking, that's a low-resource activity. Think of imposition. Self-imposing while host is doing something else is very hard and also dangerous because it drains a lot of mental resources. Show me a tupper that self-forces visualization-related stuff. Generally all this passive stuff while doing something else, whether it is initiated by host or tupper, is super ineffective compared to active forcing where all attention is focused on interacting with tupper(s). There's simply stuff you can't do on your own no matter how independent. It needs coordinated effort by both sides.
