>It's a harder problem, but civilization is essentially built of attempts to solve such problem.
I fundamentally, emphatically disagree with this. I think it's a weird rewriting of history to think that "Civilization was built by trying to stop wealth transfers within powerful families".
Do I think a lot of wealth is trapped within a few families, and that might be a problem? Sure. Do I think that the ability to destroy generational wealth transfers is what made Civilization? No, and I think it's absolutely crazy to think so. It ignores every great family in history that did everything from win wars to build railroads.
