In a previous post I theorized that the Rumbar pirates were attacked because they knew how to play Binks' sake.(https://www.reddit.com/r/OnePiece/s/lQSd0h1Kor).

This is an extention to that theory.

Remember Luffy singing the "Moron Song" back in Skypea? He comes up with songs pretty easily.

What about him becoming friends with the Kuja by singing and dancing? He has a pattern of befriending people by being the heart of the party.

And for sure you know how exchanging a cup of sake is synonym to becoming brothers in the world of pirates.

What if, just like Oden, Joyboy wanted to set sail to an adventure outside his home country/island? The rulers of the 20 kingdoms considered this a transgresion and labeled the people that did just that as "pirates" (or maybe they labeled themselves) because they had complete control over passage between countries/islands.

Now, after him, different islands or races had their own pirates; the more notorious ones were the violent and plungering ones, giving them all a bad reputation.

Let's go back at to what Luffy considered a Pirate: "being free". Joyboy probably thought the same, but when he visited new islands, people were wary of him just like how Drum islanders did not trust the strawhats.

He liberates the countries, tribes, races that are being opressed and enslaved and they celebrate victory just like Luffy and co. do in their era.

Maybe finds this top notch sake (or could it be the first sake ever brewed?) with a Wanoian or maybe Binks was his equivalent of Sanji and had a lot of it on their ship. Joyboy shares Binks' sake among people and they all sing and dance (they have never been drunk before!), becoming friends in the process and changing people's perception of what being a Pirate means, even wanting to go sail somewhere too!

The 20 kingdoms starts a propaganda war so that citizens would think that maybe they had a legitimate reason to be protective as there were some legitimate dangerous pirates out there developed the marines (with a different name).

Thus war broke out and the main enemy was Joyboy's crew, having members of different races and nationalities (minks, wano, buccaneer, lunarians, fishman, etc.) that were liberated and because they were turning other people into pirates by partying hard with them.

I also theorize that this same formula is how Joyboy got his crew formed and it will probably parallel how Luffy met his crew. For example, just like Luffy and Roger meeting Zoro and Rayleigh, Joyboy met his first mate by chance and by either doing a good deed or something badass, having fun, drinking sake, partying, etc. These mates become pirates, after being against them initially.

Joyboy comes up with songs pretty easily too! So he invents Binks' sake and it becomes an anthem of liberation.

Sadly they lose the war, the song is prosecuted and in the modern era only new world pirates know of it.

What do you guys think?
