Nobles draining gold for their families are the curse of many realms.
Kick them. If you allow that to happen, either you don't care for the realm or it is still a net benefit for the realm.
The "funneling" of gold out of a realm for personal profit or to aid your other character somewhere else is fully intentional. Its purpose is to create conflict. Absolutely nothing in the game says you have to take it, you know?
