This seems like the way to do it when pioneering a new technological approach in an entrenched industry with an established status quo. The incumbents must be dragged into the future by their hair.
The aviation industry (for passenger planes) is people that purchase flights. Evidently, sufficient people don’t value the time a Concorde saves with the extra operating costs, and they don’t value the advantages of the A380 versus the disadvantages, such as time spent transferring to smaller planes.
It would take a lot for me to prefer a longer flight with more stops than a shorter non stop flight.

Not sure it makes economic sense but good for dick comparisons :-)
