I wonder if they could supplement their income by being an ISP? the "last mile" is (apparently) the single biggest cost in that industry as well. For the low, low cost of a few fibre lines (which can snarf down 100s of gigabits these days) you can provide "last mile" services to anyone at the end of your tunnel thanks to 5G. If you got even more fancy, design the system so you can drill into it anywhere along the way, and robotically add new taps (not to the fibre, but to copper or microwave lines) along the way. They have directional drilling already for drilling under highways or angled oil/gas pipelines.
