That kind of money, even if it goes to a single person, doesn't get taken out of the economy. No one puts it under the mattress. It's invested, so it's basically given to other people in exchange for a promise of equity / future returns.
It might not be the allocation of capital we like, but it doesn't disappear.
Well, there is a financial 'sink' - stockpiles and ammunition or other non-reusable military gear are basically the definition of money 'destroyed'. Their political value is almost non-existent actual money. If any, at all.
