How did Oden get to know that Roger died when he was in Wano? The Beast Pirates specifically made sure no information got in , doesnt mean Momo has to do that. Hes protecting Wano from outside forces, possibly the World Govt. Not the news lol.
Citation needed. Else this is just headcanon.
The importance of opening Wanos borders has been stressed since Zou and for more than 20 years. It is basically the will Oden passed down to his family and retainers. Momo doesnt need to go anywhere to learn anything.
All I see is elaborated Momo4nakama arguments which arent even coherent.
