Obviously you're being sarcastic - you're right, the money gets spent eventually. But not by the billionaire. It gets spend by his kids, and his kid's kids, and so on, for generations. Meaning money that should have been taxed once in a single year is instead taxed over the course of 200 years and increasingly so on tax-exempt consumption. Meanwhile, that tax-free money is being used to invest in rent-seeking enterprises, meaning the cost of living for everyone else is being driven up. It's essentially a free loan from the US government for decades upon decades.
