Even if you had a mesh network, global low-latency communication requires undersea cables, and regional high-bandwidth hubs. Besides the undersea cables, local hub-and-spoke networks are needed to provide low-latency regional communication. Centralization of network infrastructure is shaped by the physics and capital costs of communication technology.
