I agree that the gameplay loops need attention, but what you've mentioned is basically more content. POI and geography additions won't change the loop.
- Combat needs to be seriously improved. It's cool that they added more weapon abilities, but it's meaningless when AI creatures are braindead. Creatures should attack using their evolved abilities -- whether that's pouncing, clawing, tail whips, shooting poison spit, whatever. They should be smarter... groups of carnivores should use group tactics to take you down. Stalking animals should be able to effectively stealth from your view and track you. Some creatures should be boss-level; creatures in general should have rankings of difficulty. Ground combat should feel more like a FPS game.
- Add combat against alien NPCs, not just creatures.
- If I become a friend of the Korvax, that should have benefits and consequences. Factions should actually mean something, and participating in battles should have clear benefits for success (i.e. exclusive trading contracts, rank upgrades, etc.).
- A procedural job/mission system for cargo hauling, smuggling, fetch quests, bounty hunter jobs. This is IMO the most beneficial change they could make to the gameplay loop.
- NPCs should actually walk around, get out of their ships, mine things, drive around, attack you.
- Trading system should be more dynamic. Disrupting trade routes between systems should cause item shortages, etc.
- Pirates should be an actual org that you can join and go on raiding missions
