One of my favorite themes of this game, whether it be intentional or not, is waste.
Everything about this game is a statement on waste in the universe
You have literally quadrillions of planets, full of beautiful scenery, interesting "life", sights and wonders unique and totally your own to behold and no one else's to see, and you're supposed to skip like 99% of it, stopping only to suck up the resources you require, to use the environment to your ends, and then cast the rest off as chaff.
Its a statement on the disposability of life in general. A bleak view where that which is most beautiful is also most worthy of being tossed in the trash.
