As for getting utility sizing right forever so that they never have to be dug up again, that's highly impractical as communities change - they grow, shrink, densify. Industries can move in and out of an area changing demand. Regulations change. Water mains and sewers age and fail and are replaced on a schedule. When new service connections are added, workers have to get to the main. And if they're in a tunnel large enough for workers and equipment to remove and replace utilities, we're talking a subway tunnel under every road and large access points every thousand or so feet. Tunnels will also deteriorate, flood, etc.

I disagree, and condemn your assumption that things are done the best way already. Despite everything, you still trust the authorities, in business and government. You do not see the possible as a result, you shun new ways of doing things, because you trust authority. I think it's a baaaaaad philosophy myself.
