Public transportation doesn't work just because all the jobs are in one place. At best this creates a transportation system that craters to business and not to social interaction (since its inherently a spoke model with business the hub) Also in this business-concentrated city, the synergy you describe (and I agree exists) is set up to benefit business. What about synergies between people? Better small, concentrated, cities as existed before the automobile that, had jobs scattered throughout them. (To be clear cities’ downtowns are always more commerce oriented, the agora or the forum come to mind. But go to Rome and see how small the forum of the largest city in antiquity is. Place of business wasn't restricted to one place)
