Small correction: Them sitting on it and growing isn’t quite it doing nothing - for it to grow, the money has to be somewhere in the economy “doing” things. Then the rich person gets money for doing nothing because the company (and by extension its workers) are partially “theirs”.
The benefit of a wealth tax is less freeing up that money, and more so not enabling rich people to spend the money they get for doing nothing on excessive luxuries that only serve to pollute the planet and take up resources that could be used for useful things (and also doing something against excessive wealth accumulation in general, which is imo capitalisms greatest flaw - money leads to more money, and money = power, and we are living in the reality resulting from that)
