The game elements you mention are in thousands of MMO's all over the interweb. I can see no reason for FD to create what you can already find elsewhere. Let Elite grow with it's unique outlook.
This is the problem, it is not, because the original gritty universe that "they said" they want the galaxy to be is nowhere to be seen.
For example;
Fuel scoops - Potentially could have scooped dirty fuel from the Suns, cleaner fuel from gas giants and finally clean fuel from stations, thus the dirtier the fuel the quicker the engine wear and tear. This could have given explorer ships unique modules (like the luxury modules for the passenger liners) that made them more efficient for scooping and enabled to travel deeper into the galaxy. Of course eventually they would have to go back to the core to get real repairs or blow up losing everything.
This could tie in the likes of the Hutton Truckers, who would haul equipment along supply lines to to help the explorers go even further into the unknown, seeing as we have fuel and collector limpets, why not basic repair limpets that partially repair engines and the ship integrity. What about if war breaks out between an alien civilisation... the same mechanic, reloading and repairing ships, fuel lines need to be maintains, explorers become scouts... It adds mechanics to the game that enable players to play together to achieve a goal etc... OR if they want to solo, fine, you can do it, but don't expect to do it better than a group working together, like exploring.
This means and explorer could put himself in serious trouble if he gets to greedy, and the best explorers can it take as close to the limit as possible and know when to return.
Trade - One of the original ideas for trade was that the best trade routes would be between the rim and core systems. Slaves, machines, tools etc would transported to the rim systems resource extraction sites, whilst the raw materials and precious metals would be transported to the core systems.
This however would be dangerous, as the rim system would also be pirate territory as the core systems would have high security and be far far safer for the trader. Giving the player a choice between smaller profits, but far safer trade routes or richer more profitable trade runs that are far more dangerous.
Alliances - Alliances should mean something and have pro's and con's, you are not in a million years ever be able to rank to King and Rear Admiral at the same time. It would never happen. If anything, if you are a king of the empire, you would be highly unliked by the Federation/Alliance and maybe some independent systems.
This also means it would have a direct impact on engineers as Imperial engineers would never give high ranking Fed/Alliance/Some independent players the best module mods if any at all... This bringing real consequence to the game and the choices the players make.
Pirates - Pirates should be forced to make more use of the pirate bases through out the galaxy, in some cases, secret bases that are only known to high ranking pirates (yes pirates should have ranks too). Obviously, if you are a well known Pirate and depending on where you operate, you maybe been banned from docking at or all Fed/Alliance/Imperial stations, because you have a reputation. This would make it harder for you to get ships and upgrades, sitting in with the notion that pirates are bottom feeders, feeding off the riches of the trade routes etc.
It also means proper C&P and missions specifically for pirates given out at earned locations (I.e. hidden pirate bases)...
Even bounty hunters could be catered for.
Ranking - Ranking needs to be proper structured military careers, with some rewards being access to specific engineers, whilst actually earning your rank and really taking part in military missions and wars.
It may even be the case that it will involve piracy in enemy faction territory, so privateers, just like the old Royal Navy privateers that hampered French boats hundreds of years ago. Fed pilots doing pirating in Alliance systems to undermine them, for example.
It just goes without saying so much can be added to the game, but they refuse to do it, because of this philosophy that a player should be able to do what ever he wants when he wants with no consequences, that ultimately leaving game feeling shallow and baron of perceived game play, because of this wishy washy mentality they have that has left game feeling so incoherent, unbalanced and broken.
It is really sad to see the decisions the game designers have taken, from what was originally sold to the player that got the game started to what we have now. They are just very lucky that they have no real competition at the moment and that business men pushed for an early release of no mans sky, when it was clear that the game was clearly not finished.
