That particular tunnel in that particular place was worthwhile compared a surface route, which could only have been a long detour. By low hanging fruit, I mean a favourable cost to benefit ratio, not easy to do in absolute terms,
Isn’t that rather assuming the conclusion? I don’t actually buy Eliezer’s suggestion, but by making it he’s essentially saying that large-scale transit tunnels would have a favorable cost-to-benefit ratio after adjusting for overhead costs.
