Real identity verification would be useful in peer to peer interactions. A trust is built up within users with verification. Also you know that you are dealing with the real thing not someone pretending to be me.

But I would much rather leave verification up to the choice of the user. For some people verification can cause complicated legal issues with government or company policies. For example one company or government may consider a blockchain blog as an illegal activity. In some company contracts the employer is not allowed to engage in any money earning activities outside of the company. Verification would put those people in danger of losing their job.
