About the large crew weighing down subject, isn't it obvious? I mean, imagine you travel the world in a group of 10 vs a group of hundreds or thousands. Don't you think your mobility is that much easier in small numbers?

About the armada structure, if you reference the WB pirates or BB pirates, each head of divisions are a significant member of crew (like Marco, Jozu and Vista to Whitebeard and Burgess to Blackbeard). Let's say later when FI officially goes under the Strawhats, will Luffy create a division, assign one of his current nakama (leave Jinbe out of this at the moment) as commander and leave the division there to protect FI while he goes off on adventure?

Luffy's intention to claim FI from BM is the one thing that contradicts my blog here (I purposely left it unmentioned but you see through it). At the moment, I choose to think it was a slip of tongue during his heated exchange with BM. I may be wrong about this, I'm aware.

Lastly, claiming an island is not the same as recruiting a nakama, mainly being a nakama goes together with Luffy during his adventures but an island stays in its locaition, open to threat when owner is away.
