Earlier quoted context omitted.
My main (mild) criticism of the now-complete Andor->Rogue One arc is that it only put its toe into the waters of the Death Star. Giving that concept a thematic heft well beyond its Flash-Gordon-supervillain origins appeared “fully armed and operational” in the story, but in the end it barely rises to subtext.
But there is no conflict, no interest, in exploring a building site. What are you going to talk about, contractors installing pipes? How they get the best canteen food? It's actually better for the Death Star to be unseen, so that its full horror can only be imagined - and hence, becoming greater - in our minds.
There’s a version of Andor that does a bit more than hint that the Death Star is the ultimate (and ultimately doomed) metaphorical reply to Nemik’s manifesto.
In the final analysis, the Death Star is not about power. It’s not about control. It’s a choice, meant to be the last choice for the Rebellion: Submit, or lose everything you love, everything you were, are, will be, in an instant.
But, in the end, it’s this totalizing impulse that is the Empire’s critical weakness. There are always cracks in the edifice of tyranny. Other choices.
