Maybe a reality where every person on Earth is register in some database seems scare for some people, I think that it would be a really useful thing, considering also that the data is stored in blockchain and is strongly encrypted as this project aims to do. It will be encrypted and only you can give access to it so I think it will be a better world with a lot of legal things taking place much easier and faster.
Indeed If the data is being decentralized it has a lot of useful possibilities, that should benefit significantly in the future when technologies are already developed. It is secure the data and protect the privacy values. It's completely the opposite if the 'databases' is fall to the centralized entities. Which is I'm sure it will be utilized by the corporate.
