Yeah, it's a great achievement. However, have you seen the aircraft? It's far from being a practical, every day plane. In fact, my first thinking was: "What's the crosswind limit on this one?"
Anyway,
AFAIK the main thinking is that aircraft like this are able to function as a fast replacement for satellite launching. For instance to provide instant telco facilities in a disaster area. Sounds fair to me.
(And to be honest, the Wright flyer didn't have much of a crosswind limit either...
)
