Agreed about the domains. To add to this, for me the main problem aren't even the domain registrars, but rather the certificate authorities. It is madness that any certificate authority can issue certificates for any domain! With blockchain domains, you can put the public part of your certificate on the blockchain and no one has to trust any third party to issue certificates - the domain owners issue their own certificates and they're guaranteed by the blockchain. A whole useless industry would become obsolete! (Eg https://handshake.org/ https://handshake.org/ attempts to do this. Disclaimer: I'm not a totally disinterested party :)
