The big benefit of being "not a plane" is that your emergency measures can be built around that concept. There's also a big benefit to only moving 30 people at once - terrorism looks for mass casualties or mass hostages. Blowing up a hyperloop is basically like bombing a bus - no one really bothers to try.
The big benefit of hyperloops over planes would all depend on how quickly you could brake those pods and re-pressurize the tube to let people escape. Because that's something you definitely can't do on a plane and it governs most of our thinking about them - if anything happens, you're possibly over an hour from being able to land anywhere and no one is able to get off quickly.
