Is it more expensive to home-run every home than to put splitters in the neighborhood? Yes. Is it enough more expensive that the tradeoffs cannot be overcome? I remain unconvinced. This completely depends on the area and the goals of the network. In most cases for muni networks back hauling everything is more expensive.
Slightly more expensive in the short term, yes. In the long term, no, especially if you consider the opportunity costs of _not_ being able to deploy new technologies in the future--something only home run dark fiber can guarantee.
Handing out connections at layer 1 is both more expensive and less efficient. Its also extremely wasteful (which is why its more expensive) since your lowest unit you can sell is a fiber strand whether the end customer wants a 3 mbps connection or a gig its the same to the city.
So what? How any particular fiber happens to be lit is irrelevant to the muni--and it doesn't change their cost structure one iota. Dark fiber is dark fiber.
I'm not saying you shouldn't sell dark fiber, I'm saying that in 99% of the cities you can't build a business model around doing just that unless your city doesn't want to break even on the build and maintenance.
As a private operator, no, you probably can't build a business model around that. A muni has different economics, though. At the cost levels being thrown around here, it doesn't seem like there would be _any_ difficulty in breaking even, which is all a muni needs to do.
