Do you really feel that going all over the planet and turning the crust to sand is a viable long-term solution? Many mining engineer types and even geologists see no problem with this approach, but consider Appalachian coal: just because they can "put that mountain back together just as before", the result is far from the original. It's like the policy of "moving" wetlands to ease development in my area; almost looks ok, but the result is a local bio-disaster.
