Speculations How Luffy will open the borders of Wano

[Mlzz]

the best way to open wano country would be for luffy to destroy wano waterfall at the same time he defeats kaido with his last attack.

the waterfall is an obstacle for the opening of the country it certainly constitutes a natural shield but once the pirate SHs have won this war they will take the role of protector of this island
and maybe even the revolutionary army will base their HQ there

You just forgot that there is a special entrance which is hidden. Just need to unhide it.

I guess Luffy will open them by freeing Wano from the threat of Kaido, but Zoro will be the one to kill him off.
