Ok, but is it really infinite? It seems like only a handful of players even care about the family wealth rankings, and if those few want to put all of their gold into family wealth, let them. Most players don't do that because there are more interesting things they can do with their gold, like building an army. Still it's a game about choices. There's no wealth cap in life and I don't think there ought to be one in the game either. I do however like the idea of giving players more things to spend their money on.
