Reminds me of more than one sci-fi book!

I think of the Death Star as more building like and the volume of material surely means cost comes into it, steel is more cost effective.
Steel is more cost effective for the teensy little building projects we use it for currently, but aluminum is a larger portion of Earth's crust than iron is, so in truly massive quantities might it be easier to get at?

(That still assumes, for no particular reason, that we'd be mining it from Earth instead of from asteroids, of course.)
The world is so exquisite with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far to look death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides.
