Grief is as close to PVP as we're going to get with this, so changing up your plans and approach is a good thing not only for some one trying to grief but for the players on a planet trying to protect it.
being able to trash a planet and screw everyone over could be fun for a lot of people. What would also be just as fun is if said person broke say 2/3 laws, it would allow anyone else to go over to their claim and destroy it. To keep this fun though the person braking the laws should also be able to defend their claim.
Now I know this might annoy the hell out of players who want a more PVE role, but a server setting or description of this in the server lists would be nice.
On the last server I played on I wanted to harvest all the important wild plant life then just sell it, as the player base is very low I quickly realised this was a bad idea, felt bad and ended up planting needed resources close to spawn.
