A group of people is de facto responsible for a result if it is a purposeful result of their deliberate and intentional joint actions.
@minnix, that is the definition of de facto responsibility. It is meaningful concept outside of a legal context. Ellerman's theory is a theory of how the legal system should operate. However, he does draw an equality between the tenet of imputation and the labor theory of property. I would recommend anyone interested to read his other work
Socialism vs capitalism is a false dichotomy. There are other alternatives like economic democracy or mutualism where all companies are democratic worker coops. There are other critics of capitalism besides Marx such as the classical laborists like Proudhon and their modern intellectual descendants like David Ellerman
