The only reason people are after momonosuke is because of his father's ties with Roger. And so far only Kaido and his associates are after him. Kinda like when Crocodile wanted Vivi dead, and Strawhat pirates were asked to protect her. And it all resolved when Crocodile was taken down. So, when eventually Kaido and the shogun are out cold, there will be no other pursuers.
