Why is it in the public interest to know who owns a company? Sure for specific groups of people, transparency is in order (elected politicians etc.) but wouldn’t financial disclosure laws work better? Why isn’t it the general public’s prerogative to know that I own 5% of a shell company (LLC) set up specially for the purpose of pooling an investment in a new venture?

shell companies are just companies, suppose the vast majority of which are formed for perfectly normal reasons,
