Ok this might derail the thread but I gotta get into this: Yes he is right about the creativity aspect, but he's forgetting one major thing, that just started existing within this last year: which is the advancement in AI technology which also influences the "studio magic" that is possible.
With the advancements of AI technology in just this year alone (it's in it's infancy), Axl can pretty much record and sound like he did on Appetite, aslong as he can still hit the notes (which he can, albeit in his clean tone). He didn't lose his range, he just lost the rasp which is really demanding vocally, and of course you can't keep up that singing style for 30+ years. This is the reason why people like Mick Jagger and Steven Tyler still sound so good, they sang more with their natural tone.
But now in a studio setting, he can record with the clean vocals and apply an AI created Axl voice filter on it, which works kind of like a guitar effect pedal (but just on his recorded voice instead) and have him sound like his 1987 self with the rasp completely added onto the vocals by the AI which works by feeding it with soundclips of his isolated studio vocals from AFD/UYI. People are already doing this with other singers, just applying an AI Axl onto the voice and it sometimes already sounds dead on, so when he does it with his own vocals, it'll sound pretty much perfect.
So GNR can release as much music as they want, aslong as Axl actually starts working on it.
