I like the idea. I'm not sure about a blanket progressive tax on family wealth, though. I'd prefer taxation stay player controlled. Realm-wide or region-wide control would make for interesting relations.
Over my dead body. This would make family wealth a risk-free gold-transfer system. Let me repeat: Absolutely any proposal whatsoever that results in the tax ending up in realm taxes will be flat-out rejected without discussing details. Period.
If family wealth gets taxed, the taxed money will vanish. Period.
