Should America build a Death Star?

"I wish to address the most important policy question of the millennium: Should we build a Death Star?" Yes, I realize this Washington Post piece by Gregory Koger is big fat pile of flaming linkbait, but at least it's not a 12-page slide show or a top ten list. His economic excercise is inspired by an estimate made by students at Lehigh University that "just the steel for a Death Star would cost $852 quadrillion, or 13,000 times the current GDP of the Earth."
