I also think buggy will receive a shichibukai position and he will accept. He does not have much of a choice anyways. Even if he had level 4 and 5 prisoners following him, how would he stop the hordes of marines from taking the fight to them? I could see buggy getting past a marine battleship thanks to his buggy and muggy ball but how would he deal with powerful marines? Only chance he has of avoiding a ridiculously huge bounty is to get the title. Once he gets the title he does not have to do much. Shichibukai don't have to follow orders. Shichibukai are there mostly to scare other pirates, their presence is mostly symbolic. As we have seen before, even attending meetings is not mandatory and they are barely required to be friendly with the world government. If buggy gets a shichibukai title then he is basically set for life, he does not have to worry about marines anymore. He does not even have to fight pirates. By staying in the safer half of the grand las "roger's former crewmate, almost a brother to the red hair, shichibukai, ally of the WB pirates" he has more than enough to scare any pirate. Very few would fight him and those who do would have to deal with the horde of prisoners who escaped with him.
