yeah, its pretty wastefull. if you dont want to mod arround the problem, there is a setting in the settings.txt that will turn off asteroid depletion (a good thing imo, it would be pretty hard to mine out an entire asteroid field. about as hard as mining out a planet).

i would also be interested in seeing if you built a system value improvement facility (religious tech, i think) on a created planet in an asteroid system, if it would increase the value of the asteroid fields as well as the planets.
