I agree that is the best approach. And so did Kevin Rudd. You're describing NBNCo, and I think that's been a great achievement for the nation - despite a decade of lies and resistance from the coalition about its successes. The two big issues with this approach are:
- What we saw with the NBN: The political party who doesn't build it will smear it and taint it with the populace.
- Eventually, the government could look at this lovely piece of infrastructure as a huge asset that it can sell for a quick buck to fund some shiny thing.
