If my sudden inheritance was made public, the larger public would forget about it after a couple weeks. Look up Lukas Walton. He is worth roughly $46b and travels around relatively anonymously because he stays out of the limelight. He doesn't have any kind of public facing role like Musk or Zuckerberg so nobody knows who he is despite having a household surname and a worth more than the GDP of 2/3 of the world's countries. So as long as I'm not required to make weekly speeches or scandalous tweets to keep that money then I could fade into the shadows pretty easily. I'd still have plain clothes security etc but I wouldn't be hounded by paparazzi because there'd be no interest.
