what case are you referring to?
I think though the only reason that works is because Berkshire is buying great businesses with great managers at the helm. When you get into turnarounds/distressed businesses you end up having to roll up your sleeves and get involved much more frequently.
For Berkshire Hathaway, that service is liquidity. Buffett provides businesses with a large lump sum of cash, enough to ensure that they and their heirs will never have to work again unless they choose to. In return, they can continue running the business exactly as they did before. For many entrepreneurs, that's a very useful service.
