This ended with /s but DNS and other global namespace management systems are actually one of the problems blockchains solve perfectly. We all need to know what the value of some key->value pair is and have that information always available and easy to update. Blockchains handle data distribution natively, allow updates from authorized parties, and have 100% uptime. Transitioning DNS to something like ENS is something with lots of upsides and few downsides.

Take a look at https://ens.domains/about and https://handshake.org/
