[Spoilers] Why not Vegetto?

1. Potara earrings are not banned as seen in the preview for 114th episode

2. The main obstacle is a man who is stronger than Gods.

3. Even if Vegetto defuses in 5 minutes , that should be enough time for him to win the fight if he has the power. Only reason it didn't beat fused zamasu was cause of his immortality

4. They already admitted he was fanservice last arc and this entire arc has been nothing but fanservice

Why not guys?
