Cool, then let's do this:
This whole thing about MGSV not having a story is complete hater BS. The game has all of the trademark Metal Gear story beats. They're absolutely not in the same place they've always been, but they're all there.
You have Skull Face as the main villain with an apparent simple plan: sell nukes to small nations in order to undermine the world's super powers. His plan, in true Metal Gear fashion, has more to it than meets the eye: he's a victim of colonization and wants to give every tribe and every race a fighting chance against any and all invaders.
Which leads to the ambiguity in Metal Gear's villains. Not only is Skull Face's plan ultimately good (though his methods are highly questionable) but the the secondary villain is also left very ambiguous at the end of the game.
Metal Gear's secondary villains usually overshadow the main villain in cunning and power - a role which is usually occupied by Ocelot. MGSV's secondary villain is particularly special since it's
Ocelot is still being Ocelot, even though his on your side. In a classic Metal Gear move, he's revealed to be deceiving the player at the end of the game to help the secondary villain.
Quiet, as sexualized as she may be, is one of the strongest examples of gameplay-driven storytelling. At the end of the game, in the originally released version, she makes her own decision of leaving you. For good, forever.
Huey has an amazing story arc where he's revealed to be yet another villain in the game. A pathological liar, someone working from within your own organization.
And these are just some of the examples that come to mind, MGSV gives us a superb cast of complex characters that constantly add to the depth of the apparently simple story of catching the bad guy with the nukes that destroyed everything we built.
So, no, MGSV can't be criticized for not having a story. It does have one and a pretty great one at that.
It can be criticized, however, if you didn't like the story, which is fine.
But saying "I don't like Kojima's writing" is a completely different statement to "Kojima can't write".
