He would let his customers decide how to light it and what to carry on it. The economics hinge on the fact that glass is not a precious commodity. Once MMFN figures out its initial routing plan in a city, it pulls an irrationally exuberant number of fibers. Plus, it installs more empty conduits for future fibers than it can imagine ever needing. Once this infrastructure is in the ground, the cost of each fiber is close to zero.
Customers are delighted to buy fibers that are priced far below their cost of new construction.
MMFN's ultimate goal is to eliminate the tariff system so the newly abundant marketplace determines the price of communications. MMFN wants its customers to run out of capacity so they have to buy more. Dark fibers, like airline seats, won't make money if they're left empty. The more carriers there are in a given market, the better. Thus, MMFN favors unrestricted competition, low end-user prices and widespread broadband access.
