Regarding the first part of your comment; there are perfectly legit reasons you might not want your full contact details published on a database accessible to the wider public. Just think of political dissidents in other countries or people at risk of being doxxed for various reasons or simply not wanting that information to be public at all.
Regarding the second part, it's not viable to "make new and better". There is new and maybe better but nobody is using it. The ICANN has a quasi-monopoly on governing the DNS registration rules on the internet. It's like saying that if we don't like Facebook we should switch to Diaspora. As much as I'd like to, Diaspora doesn't have the network of Facebook or the reach which is an immediate nogo for a lot of people. Not recognizing that is simply ignoring the reality of many people's lives.
