The difficulties of the route did seem to be ignored in general. The environmental constraints are not some minor triviality. Even if the tracks are in the air and have a small footprint you still need to get access for large vehicles in potentially sensitive areas. Getting into dense cities tends to depend on very expensive tunnels, highly contained pinch points, or tight corners. Ultimately you have thousands of interest groups who will treat Hyperloop with the exactly the same skepticism as rail and solving those problems will cost just as much.
