This is one of the places where I'm skeptical; I anticipate a lot of people would have issues with this thing passing overhead, and I have my doubts that they could be overridden, at least without some expensive legal wrangling. I admit I'm not quite clear on how rights for things like power lines work; I realize that those do get built, despite there no doubt being plenty of people who would happily oppose that if they could, but these tubes would be substantially larger than power lines, and I expect the opposition would scale up similarly.
