Magnus' longevity has more to do with his willingness to continue competing than his actual skill. He's been pretty vocal about his issues with FIDE so I can see a world where he stops participating in FIDE events to focus on non-FIDE events that he enjoys more. He's already withdrawn from the Candidates which qualifies you for the World Championship.

Magnus not participating in FIDE events seems to have absolutely nothing to do with his longevity, it just means that FIDE is no longer meaningfully hosting THE world championship because they failed to attract the talent.

		Yeah if FIDE crowns some other champ without Magnus people wont think oh wow Magnus lost the spot, people will think oh wow FIDE lost the spot of being the kingmaker. chess.com is probably the more credible org for global rankings anyway
