I think this and future models are likely to find profitable niches. Taking heavy loads into and out of inaccessible areas is one, especially if those areas are remote. Emergency supply into areas that have suffered disruption of normal routes (earthquakes, floods, etc.) I’d have thought the much lower operating costs would facilitate everyday resupply of goods to remote communities.
Also, compared with helicopters and tilt-rotors, the concept seems inherently much safer. Lots of redundancy in the engine department and if the worst came to the worst, you just drift gently to earth. Even hitting something would probably result in a “boing” rather than a “SMASH!”.
The ratio of useful load to that of structure plus fuel appears a lot better than conventional aircraft.
Don’t discount tourism: when you see what people will pay for a small cabin in a ship that trundles around at sea level, what would they give for ever-unfolding panoramas and being able to circle places then land next to them and go and have a look? With the sort of lifting capability being discussed for the growth versions, you could fit a whole lot of luxury in there as well as a fair number of passengers...
