> We may need a whole separate branch of jurisprudence and legislation, dealing with situations where value (or harm) is an emergent phenomenon in a dense network, not only not attributable directly to any singular node, but also much greater than straightforward sum of nodes' values.

The basic concepts already exist in current jurisprudence, like class actions (many people aggregating together) and punitive damages (damages exceeding cause and effect losses). Don't think these concepts require a sea change, just a modern-day upgrade.
