The fact that you have multiple companies each running their own physical network (through the same ducts, no less!) is absolutely wasteful - imagine if we did the same for the electric grid, water or gas.
The physical network should be government-managed and any providers can pay for layer-2 access between any 2 points. This will prevent wasteful, redundant infrastructure.
