One off discs would not work - they need to be manufacured in quantity to be durable. Vinyl cannot be “cut” it needs to be molded. “Properly produced” in quantity.
While we are in fantasy land, I’d suggest wax cylinders. :-) actually manufactured plastic, not wax, but hey it is fantasy!
But you know, I have some faith that audio professionals will be able to keep migrating digital audio into the latest formats, which if so means digital is the only permanent medium. Records degrade with improper playback, can break, melt, be made into bowls and ashtrays, ritually burned or driven over by tractors, so what is permanent is what humans decide to make so! :-)
