Infrastructure is immensely expensive. Either you have to run new wire to tens of thousands of ppl, or you have to rent space on existing lines that belong to your competitor. Your competitor, being your competitor, is going to Katdaddy you for rent on those lines. So, either you drop multiple millions just to create what is a comparatively small region, or you pay a crazy amount of "rent" to the guy who's biz you are trying to take.
