Dead Asteroids are planets of almost no cultural and civic value, they are used as a bulwark against enemy invaders
A Dead Asteroid cannot support logistical structures within its gravity well, unless you're a TEC player with "Development Mandate" researched. There is also no need to colonize it for population needs, as it supports none, and there is nothing to actually mine from the planet as there are no metal or crystal asteroids. The only actual use for the Dead Asteroid is as a bulwark against enemy invaders should it be located in a choke point.
