I don't really want to offer a counter anecdote at this stage, because there is something more fundamental about the NBN plan than the simple "Cost for Cost - speed for speed" rationalisations of the argument between the plans broadly outlined by the Government and opposition.
The fundamental thing for me is the experience Australia had with the privatisation of Telstra in the first place, and whether the mistakes made then can be made up with a new plan.
The rationalisation of privatisation at that point and generally was that investments formerly provided by the Government would be made by private enterprise, and that costs would be borne by the end consumers who were most willing to pay for the services provided.
The main unexpected downsides was that voters even in cities were not happy with the disparity between country and city services, so a regimen of regulation was built up so high, Government became a virtual "owner" of Telstra's minimum service, but in a much more inefficient way than *actually* owning the associated infrastructure.
A second downside was the inefficient duplication of things like mobile phone towers, which provided neither more coverage, nor extra reliability.
A third issue can be illustrated with an anecdote. When a *Telstra* Fibre cable was accidentally cut, all services *other* than Telstra, including mobile phones stopped working for huge swathes of regional areas, including many which ostensibly should not have even relied on that connection. Ironically many Telstra services continued working at a slightly lowered reliability.
The ownership structure of the NBN is the real key to why it will resolve the failures of privatisation without harming its successes.
