The same is true for all infrastructure in that it gets less expensive per user as density increases. The cost to hook up an apartment building to the grid is a few houses in a suburb but services 10x the people at the same revenue per person. The cost to service a single home in a rural area might wipe the revenue out from a dozen apartments.

Frankly, I’m sick of subsidizing the rural welfare crowd. Let them pay the market price for their roads and utilities if they want to cosplay as Galt gulchers.
