When you are dealing with a city of millions does it really seem right to fish one wire at a time? That means terminating the wire at the home too. With multiple ISP's how many of them would need access to the "Main St" section at a time? The cost of booking a time, sending a worker out to fish and terminate possibly kilometers of wire per customer as each customer signs up would be a logistical nightmare. Then what happens when the customer leaves you for the other guy? Never mind the cost differential of running one wire vs bundle of wire.
