This is a compelling argument but there is an upper limit of how much wealth can be intrinsically tied to a person. When we start talking about 8, 9, 10, 11, even 12 figures it's really hard to argue that the value of the wealth would diminish if it was distributed among more people. If anything I would expect people with more modest amounts of wealth to be more motivated to manage it (rather than hiring someone else to do it, at which point there is no intrinsic personal connection).
