There is no jump, there is no magic hearthstone, this is a sci-fi game based on certain rules, not WoW based on magic, so we follow the rules of the pretend physics otherwise the entire thing becomes broken.
Let's clarify the wormhole thing. The Fleet Carrier doesn't go through anything when it moves, yes you see a lot of smoke from the outside and the illusion of it moving into a wormhole, but that's all smoke and mirrors, in essence moving the Fleet Carrier is a database change and when it moves it just dissapears from one location and re-appears in another, all the noise you hear inside and the sights you see outside are just window dressing on a database update. You can't follow it because it's not actually moving and any database update for the FC can't possible encompass the same thing for what are essentially exterior objects.
Now the wormhole things? How do explain that without making it available from any station or megaship for any player? Indeed it's just straight out magic and a bad fit for the game, that's not going to happen because there's no basis for creating remote witch space tunnels in the ED universe.
Also, there is no end game to Elite Dangerous, that's what creates all the complaints about grinding, people who think they have to grind to get endgame stuff and when they get there they find it's just stuff, nothing special, just a big expensive ship that costs them money to maintain and move.
