Train cars must be connected to each other because of how trains work, whereas the Hyperloop pods are separate from each other. I haven't yet seen anyone actually crunch the numbers on the proposed weights for the Hyperloop (which are in the PDF) vs existing light rail solutions. You certainly can put a light rail up on pylons, it just might be a lot easier/cheaper to do so with the Hyperloop. I do think he's playing up the benefits of using pylons too much, since the real benefit here is the 35 minute travel time and affordable ticket cost.
