Sorry, I had to laugh, a game that's been in development for 10 years plus and for which "backers" (future players of the released game) have invested not just hundreds, not just thousands, but in many cases 10's of thousands of actual dollars, won't have a ship that can do that? Or that future players will be happy buying a ship that can't actually go anywhere? Not sure what you think is going to happen if it is ever released, but everyone, and I mean everyone, will be immediately charging out to find everything! That happens in all MMO's with limited maps, because everyone knows there's only so much to discover and once it's found it's found.
Elite Dangerous on the other hand can continue to release new planets and new types of planets, new bio and geo, whatever they want, for all intents and purposes forever because the galaxy will never be fully explored in anyone's lifetime!
