That place is a haven that's right next to the HQ, and every strong pirate has to stop there on their way to getting to the new world. Furthermore I don't think that back in the day it was easier to get through there, have Rayleigh coat your ship and be on your merry way with no marines trying to stop you.
You're a fucking retard, that's the whole point of having your ship coated to go through Merman island. So that they won't have to deal with the Marines. If the Marines bothered sending Admirals to the Archipelago every time, then they would simply have the entire area under lock down. Do you really think every single one of those Pirate Captains that are aiding Whitebeard could take on an Admiral?
