Concorde stopped flying for lots of reasons, not the least of which is that BA was the only one flying them by the end. In a different world, had there been a robust cargo program (and a reason for one), it would not have been on British Airways to run the program by themselves and the program would have continued. This is hypothetical, of course, but the rockets are flying to deliver cargo (and people) to space anyway, so there's a lot of expertise being built up that doesn't depend on a passenger service.
I don't know if rocket passenger service will ever happen or become routine, but there's just so much to the Concorde story that simplifying it like that isn't a good case study that does the program justice.
