Assume you think the government is in a better position to spend that billion than the billionaire is to figure out what to buy or invest their money in?

I know he's out of favor with a lot of people, but would Elon have created SpaceX or The Boring Co or Neuralink, or helped start OpenAI if he hadn't had the spare billions to do so?

I'd much rather have multi-billionaires investing in the economy, and in the future, than giving additional money to the government.
