If you have an Earth Science text book look up the Rock Cycle. (Or you could do it on the web.) Rocks are constantly being produced and eroded. And by the way, it does not take 4 G to produce and erode rocks. It is a much shorter geologic process. Ever see a volcano erupt?

Firstly: theres a hell of a lot of them, the earth is rock and therefore there is are plenty of rocks to go around
Secondly: rocks are constantly recycled (on a 4 billion year basis) so even if you dig a vast pit into the earth, when it is subducted or collided it will disappear
Hope this helps

They are. I never thought of most rocks as being a resource.
