Just to awser a few of the "it's an empty game" questions, AFAIK :
Why can't we form squad ?
It's coming, hopefully early 2015 if Frontier is on schedule
why can't we own/buy/build stations ?
Explicitely not the point of the game, a choice by Frontier. This is not an "X" game.
why can we form military force ?
Several answers here. In case you speak about large military force you command, it's tied to the above, Frontier don't want to make E: D a strategy/management game where you manage large amount of "X" from afar. It's more about you and your ship, and you IN your ship. That's the kind of scale they aim.
In case yo speak about lower amount of military force, MP instances are limited to 32 players, that should be somehow enough to build some great military experience. We're lacking MP stability and predictability, hopefully to be fixed by FD
why can't we explicity join a faction and wage war ?
You can, actually. It's the whole point of the faction reputation system. You can get up the ranks of Federation and such, and get more involved into their operations. It's not a "click here to enlist" process, it's a bit more involving than that. And a bit more buggy

Again, to be fixed by FD. Seeing their responses during the Lugh experiment, they are looking into it.
I am trying to love the game as much as I can ( I am still having fun for now ... ) but it feels like a dumb down version of an X-series game. I don't care how frontier was back in the day. If today we have games that offer the same feature with more to it, there is no reason why ED should not.
Again, don't expect X level of troop/station/etc... management. It's not what FD tries to achieve
