That's a reasonable argument, and doesn't require us to agree definitions of wooly terms first
One of ED's core aesthetics is that you're a small part of a vast universe. That's quite unusual in a game, and means there won't be some of the things you'd see in a game built around mighty player-heroes. Not to say there's anything wrong with that sort of game, it's just not what Frontier are going for.
You know, I can see it from the other side of my argument: there is virtue in a little humility in game design. If players are forced to be a small part of a system, then that is a humbling experience, as compared to literally every game out there that pushes you in to become a Commander Shepard, out to save the entire universe single handedly! So yes, I like ED being "different" like that... but I would still be more ambitious!
