I think it would be legitimate to say that building is not the same as destroying, yet both are considered to be vandalism on a claim in this game. This creates many potential problems for when you are building trust with others in this game, because to prevent them to destroy is to also prevent them to build. One has a much more negative effect than the other. Because of this I'd like to propose a simple change that adds the option of building on claims alongside the options of trespassing, theft, & vandalism.
Example: I give orange colored player trespassing, and build permission on a claim, so that they may walk around and build whatever they like(including stockpiles, and planting trees/crops), but they do not have vandalism so they can not destroy anything on said claim.
Those of you that may propose that such a change is not required are likely either playing by yourself so this would never apply to you or you are already part of a large group of players you already trust so that this would also not apply to you.
