Because those of us with realms at war (continent-wide war, no less) don't want to see tens of thousands more gold taken out of their realm that could be used to fight with instead?
Not every island is Atamara. Not every realm is Darka. It's very nice that your realms produce so much gold you don't know what to do with it, but some of us actually need the gold our realms produce so we can fight.
You can do what you like with your gold. Nobody's required to send
any gold to their family unless they choose. You're also free to move your character to Atamara if that's more to your liking. It's a game about choices. You may not be happy with the choices your realm mates are making, but creating rules and restrictions to get them to do what you want, IMO, is not how the game should be played. If you're realm is at war and everybody is more concerned about hoarding wealth instead of fighting the war then guess what: you'll lose the war.
