I don't see how owner tags will help. I went on Andor to mine some and each rock you start at has an owner tag. If you leave the rock, it goes to no owner after a while. So that means while your mining one of your six, seven or eight rocks the others will have no ownership and some stealer can come by and take some.

Then you have situation two. All the rocks that fall down from the area will have owner tag for those who bombed it. That means if a friend is bombing for you you cannot mine them or if someone offers you up on a rock you can't take it either. Plus, if someone decides to go offline and the rocks are still there you'll get plenty of angry people (just like the finished trees in the farming areas). If you put a limit to how long someone can own the rock it's bad too because not everyone will be that fast (or that slow) when mining.
