For "short" (< 500 mile?) journeys, a plane wastes a lot of fuel climbing to altitude. Hyperloop has an advantage there. But for those journeys, high-speed or even regular-speed rail is tolerable. The challenge a train has in enabling those journeys is the last mile, which is why trains work in older cities. I can, and do, get off a train terminus in the town centre and walk/cycle/bus to my destination. For longer journeys, I'm not sure there's a technical case for hyperloop over a plane even with zero land cost - planes at altitude are good at what they do. The challenge a plane has in enabling those journeys is that, whilst a plane doesn't need much land in total, it needs an awful lot at the terminus. So it's a last ten miles, not a last mile. However, a good shuttle service can solve that.
