That can never scale as much as we'll need if we're serious about replacing DNS, so it's pointless to try.
But of course some people will try and have a lot of fun and make a lot of bold claims for many years.
Discussion
have you seen any proposed solutions you’re drawn to as possibly interesting directions? any strawman ideas to spitball?
My preferred solution involves creating a so-called "spacechain" -- a parallel blockchain dedicated to this that relies on Bitcoin and don't have any shitcoins in it: https://www.youtube.com/watch?v=N2ow4Q34Jeg (specifically I want them without the burning, but that is irrelevant).
There are many possible ways, none yet possible in the current Bitcoin, unfortunately. I made a prototype that worked on signet: https://github.com/nbd-wtf/soma, but this was a long time ago, and I thought we were close to getting APO on Bitcoin 4 years ago, but how naïve I was.
The question of preventing namesquatting I think can be handled gracefully by just releasing shorter name availabilities slowly, with a fixed predetermined schedule -- kinda like Runes did with the names of their shitcoins.
