I mean, apart from the open question of whether the majority of money gets moved into tax havens, if the money is out of the economic system entirely, won't it just inflate away? I presume rich people want to put their money in instruments that return interest, which means that it has to be used /somehow/. I mean, potentially just speculative assets like gold or art, but those are high risk.
