Seems to me that the name “starship” ought to be held back, for now, on the assumption that eventually, Mankind might achieve the capability of creating a craft that can actually travel to other star systems.
This “starship” isn't even intended to go beyond low-Earth orbit, is it?
Of course, Beechcraft already appropriated the “starship” name back in the 1980s, for a craft that isn't even capable of leaving the Earth's atmosphere. The Beechcraft Starship sold rather poorly, and at some later point, Beechcraft determined that it was cost prohibitive for it to support the small fleet of them that was in service. They made efforts to buy back and destroy whatever units they could get their hands on, making special deals with owners of them to trade them in for more conventional aircraft.
