This is a frequently rejected request.
The reason is gameplay balance and fun. With gold passing from noble to noble, it would be 24 hours tops until a realm has designated "gold couriers" whose job it is to make sure the frontline troops can stay in the field much longer by supplying them with gold. And I fear newbies would be the first to be pushed into that role.
It is not going to happen. I don't care what good arguments from realism or bla anyone can provide.
While I agree that it is not a wanted change, I must wonder whether in fact new players would be used for it. After all, large sums of gold would be involved. Surely wise people would use nobles that could be trusted?
