Strong sense of dejavu since Europe has been doing this ultimate beneficial ownership database (UBO) thing for many years now. Initially they wanted it publicly searchable. It was often named the Kidnap List, because that's it's main use case. It also includes charities which rich people often put in the name of their children.

Safe bet this will all be on the darknet. The moral: if you want privacy, stop being an entrepreneur, don't ever create jobs!
