How long is a ‘name’ and who gets to decide what it looks like (no system I’m aware of could capture the symbol Prince used for a while)? How long can a name be? What special characters are allowed? How many names can one person have (first/last/middle or 6-7 names, Aliases, Previously Known As)?
Within countries, some will say the government owns much of the other personally identifiable information (generally abbreviated to “PII”) for that country (probably the US among them). There may even be some international consortium that believe they ‘own’ data related to their field of expertise (but I bet there’s other consortium that would disagree with that position).
