Just to precede my post; I've definitely skimmed, rather than read, at least half the topic.
As memory serves, land specific tools are such to force interaction between lands, so that there has to be that interaction. If we take Tea, you get the herbs from LR, the water from MB, regardless how much is made you have to interact with both lands in some capacity in order to do it.
You say you shouldn't be forced to interact with others (or something) because you are a fighter, I say this is a community and that is precisely what should happen if you want to perform certain actions. This is a PvP, not a Single Player game as you seem to imagine. The players you state, did/do they play alone? Z has his tree, but also his alliance, he interacts with people there, likewise for Awii. RJ had his Drachs, and sporadically had quests for them. IaB you'll forgive me for not knowing what he's up to lately, but at least in the most part these players are not playing alone like you suggest.
Shared tools are only "useless" as you put it, because there's little to do with the resources after you've got them. What you propose will not solve this, it will delay it, and will end up a whole lot worse.
And you know that it's fully intentional that the resources bulk up right? And so transferring portions of resources isn't a good thing (or however to phrase it).
