Yes, because it is incredibly hard to bring reusable rockets from concept to full execution. The idea has been arouns for a long time and there have ben dozens of attempts of course, just as flying cars, autonomous cars, real A.I, space elevators. Concept an execution are vastly different animals, it is at least 1000 times more difficult to achieve resuable rockets than to have the idea and at least 100 times more difficult than to try it.
