Why? Operating a successful business should be remunerative on its own, or else it's not successful. Owners who don't want to do it anymore can let it become worker owned. If they don't want it, it can dissolve. What else do you need? The very concept that the end of a successful business is a big payday for its creator is itself the poison here. There is no end just another workday, success is ongoing not final. This is natural and correct.
