Ok, here's the thing:
It's funny how the biggest screamers are the ones that have the most "non" shared items?
Let's take them one by one:
GG - their tools are in an inaccessible to normal players place = shared only for few (not even for ALL citizens). What angered the community were the laws yrthilian made back when those items were created. You can find them here. Was it wrong? Unethical? Illegal? No. You have to be insane not to try to extract some profit from something that you are the only one who has it. However, they were at least opened to the idea of sharing even if for a price.
Necro - let's say that I manage to get into Necro. I cannot take ANY item because ALL of them require loyalty. Do you remember, Necros our fight from 2 years ago when you got mad at Eon for getting the shovels? You were very "SHARY" back then (and you haven't change unfortunately). You were worst than GG-ers. You couldn't stand anyone who was not one of yours take the items. Not nice of you. Not at all. If I understand the GG-ers with their fee (after all as Nimmy said, you can make a huge profit from memory stones+spellls) I really don't understand you. Another mistery to be solved :D
Loreroot - although they were the most vocal about depletion, they never ever tried to stop anyone from getting the baskets (or if they did it was only for a short period of time). As for the rest of their items, I don't remember them being cheap and not giving them to anyone who asked (Except the well known depletors :D - which by the way managed to make a deal with Loreroot. A decent one without any blackmail and such.). I was very surprised some weeks ago (or days) when Tal passed 2 shared items to No one even if the latest didn't ask for them. Tal! Just look at his Personal Request Month wishes to understand what resources and depletion mean to him.
MB - their never really had a share tool only for themselves so they are out of the discussion.
So, the issue with the shared tools is not about the possibility/impossibility to acquire them. The issue is the people's attitude towards them. I agree, loyalty based items were meant to encourage trade between lands. But this doesn't means you should cling to them with your teeth. Or be unreasonable and put some really nasty rules about renting and all that. Yes, some tools are more valuable than others. Make a profit from them BUT don't forget it's something you got for free. So don't be an a**hole and pose in St. Mary, Joseph and the Holy Spirit.
Yes, a balance must be attained. But if you start screaming that your land is poorer than another and so on you will only achieve frustration. Mur made a bad decision (it was not his first and defo not his last) or in his sweet style he started something he didn't finish. Instead of GG it could have been MB. Or any other land.
And to summarize: all lands and leaders were greedy. It just happened that GG's resources were more usable than others. So don't point fingers. You might find them broken.
