Yup, and tbh without an OGM (yet) I think there is no way Med could be considered the GOAT right now. Even less so with various flaws in her skating, like her technique. It's not just about medals and it's certainly not about scores.
I also think that without OGM, a skater cannot be the GOAT (but can be one of the GOATs although it's a very subjective title anyway). In the case of Michelle, especially in 2002, the OGM was within her reach and she did not have the mental fortitude to claim it due to her own mistakes. That is the difference between someone like Michelle and someone like Yuna, who always rose to the occasion.
One could say that Sonja Henie is the GOAT because she basically invented the sport. I think someone who invented the basics of the sport (the father/mother of figure skating?) is distinct from someone who is the greatest skater of all time.
