Haki doesn't pretend attackers devil fruit powers...It can help prevent some damage, but it doesn't stop it's effect. Otherwise we'd have situations like:


 * Magellan uses poison, HAKI, nevermind the actual physical liquid...
 * Akainu uses magma, HAKI, nevermind the sheer heat and convection forces...
 * Crocodile makes sandstorm, HAKI, nevermind the shredding inertia on each grain of sand...
 * Chopper punches with monster point, HAKI, the mass and power of the punch completely ignored...

Haki is not the answer to everything.
