You must be joking. Wealth people? Depart with wealth? Willingly?
People who fund raise for non-profits convince the wealthy to part with their wealth all the time. If we changed society to make this the way to have a legacy as a rich person, then it would happen. Cultures around the world have convinced their wealthy and powerful to do far wackier things than endow an intentional community.
History shows us that the crazy thing to do is to try and force very smart people with lots of resources and power to do something they find distasteful. The same thing to do is to change how people think, feel, and behave, using historical models as precedents.
Well there is some success in getting rich people to divorce with the majority of their money, but as a general rule you don’t make money by giving it away. I don’t see any tax scheme succeeding if it depends on the participation of the taxed—that will be abused by the rich, who have more resources to launder money.
Getting the wealthy to depart with their money works if it's voluntary, and the impetus comes from the culture they want to be a part of. When it doesn't work, it's when other people try to force them to do it. Also, if you look at cultures where heavy progressive taxation works, you'll find there is already a communal thread of culture on which it's based.
Schemes to tax the rich and powerful only succeed with the participation of the rich and powerful. That is what you are also saying, but your view is distorted because you are othering "the rich."
