If someone is ready to finance the $68bn needed to build that high speed "train to nowhere" that doesn't answer a problem, I really don't understand how nobody would be willing to finance $6bn (or even $12bn to correct for the optimist view of the paper) needed to build an Hyperloop-like project which, even though it may not answer an immediate problem, would give the companies participating in it a considerable edge against the rest of the world on the variety of research/technology/know-how needed to build it. That alone might be enough to actually give value to the project.
