The only reason people think this doesn't work for companies is that they haven't experienced the "common goal" part -- management bureaucracy discourages caring about the common goal, instead focusing on encouraging obeying direct orders.
(And then it goes on to redefine "obeying orders" as "coordination" to prevent anyone from seeing what's going on.)
