You are talking about the same inertia that drives people to fight until they demolish a realm.
I don't think that's fair at all. First of all, that inertia at least gives people something to do. Second of all, the inertia that leads to realm destruction is usually based on the losers refusing to accept defeat, preferring death to surrender. You can't ban people from being suicidal...
As for Bronnen's suggestions, I'm firmly opposed to allowing characters in one continent from sponsoring characters on another, which is what all these family gold mechanics are.
