(1) There exists a blockchain-based, decentralized DNS lookalike: https://handshake.org/
(2) Every major OS has has a way to plug an alternative DNS resolver (except maybe iOS), and every major browser has a control to switch off the DNS-over-https resolver. With any goodwill from the major mobile OS vendors, a new resolver could be rolled out to 99% of consumer devices or so, and work transparently.
(3) A new name resolution system should not clash with the DNS namespace. It could allow to copy established DNS domains (not parked) to the new namespace for a nominal fee.
(4) Many DNS tricks, like load-balancing, could go away. Running your own name server can become harder. The transition, should it occur, would not be fast.
Anything that doesn't work out-of-the-box is dead on arrival, though. I would never be willing to move my domain from .org to a system that people couldn't get to without installing additional software (eg OpenNIC.) But if every OS and/or every major browser supported OpenNIC, then I'd be willing to make the switch.
Indeed. My point is that supporting an additional name resolution system is mostly a political problem, and technically doable.without forcing people to even upgrade their OS, phone, or browser.
