Ok that's true, the Euro 2024 is the next step on his schedule, but I am sure since Ronaldo is this record junky, he will do everything to go to the World Cup as well and he will try to score the most goals as a 41 years old player at a World Cup. He wants all these records be attached to his name and he also wants to prove a lot things to his son. Now I have rarely seen a guy at his age with that level of fitness. Ibrahimovic retired at 41 and scored goals in Serie A and while Ronaldo can't break the record for the oldest scorer ever at a World Cup, he can break the record for most goals scored at that age at a World Cup. The biological reality supports your thesis more than mine for most people, but I think Ronaldo doesn't want to stop despite being a successful businessman. He wants to be on the pitch and play and earn money and recognition even when he says he doesn't have to prove anything anymore.
In fact, Ronaldo will not be able to become the oldest player to score in the World Cup, as this record now belongs to the Cameroonian Mila, who scored a goal at the age of 42. But he can score a goal in the playoffs (the record belongs to Pepe, who scored at the age of 39) and plus extend his record streak, which belongs solely to him: Ronaldo scored at 5 World Cups in a row.
That's pretty much what I said I guess? But rather make assurance double sure!
I think for him it is mostly about extending the streak and set a record for most goals scored at one World Cup at the age of 41. Whatever the record is that he can hunt down at that tournament, I think he will try to do it. I don't think he will retire too soon. He is obsessed and I am not saying this in a negative way. If he can still be competitive enough to help his team, I think it is just fair to acknowledge that and not make any suggestions to him. And frankly, if he plays that World Cup I would be curious to watch how he will be doing. It would have its own bit of excitement to see how a player at that age can do.
