In this example, it’s clear that W0 is a special node. However, the AI only deduced that because, under ∅, W0 determines W. It’s perfectly plausible that under action b, say, Hum instead determines it. Under ORu and ORv, none of those nodes have any impact.
Therefore we need ∅ to be a special strategy, as it allows us to identify what nodes connect with W. The advantage of this method is that it lets the AI find the causal graph and compute the dependencies.
Ah, I see what you mean. I wonder what kind of real-world issues crop up if you identify ∅ with no output along the output channel.
Another way to approach identifying W0 is with observational data collected by humans. Or (hopefully) with some stronger and more semantically-rich method that tries to separate the causes we really want to preserve from the causes that we regard as interference.

Agree strategies are better than actions.

I generally think of ∅ as the “turn yourself off and do nothing” strategy.
