What resource extraction scale is implied by building the Death Star I using iron density?

The complete disassembly of Earth's crust, or perhaps even the entire planet

Estimating the mass of the Death Star, even using optimistic assumptions about density similar to steel or iron, results in a mass so large that sourcing the raw materials presents an insurmountable logistical hurdle with current industrial capacity. The sheer volume of material required, calculated in the quadrillions of kilograms range, far exceeds accessible off-world sources like asteroids alone if aiming for rapid construction. To acquire the necessary components for a sphere of that size, especially if built with terrestrial-density materials, the analysis suggests a requirement that necessitates the complete dismantling of Earth's crust or, more drastically, the entire planet's mass. This scale of material procurement is far beyond any near-future industrial capability.
