seeing how luffy is using it he's able to launch his attacks at his desired object destroying them without direct contact. a swordsman equivalent would be a flying slash but that isnt ryou. A swordsman using advanced coa looks entirely different.
Heโs not launching his attacks.
This isn't even something which should be debated because it is vlearly stated in the manga.
Luffy initially states that he wants to be able to use haki to attack someone WITHOUT TOUCHING THEM. He says this by remembering what Ray did to the elephant and claims that it looked advanced.
Hyo goes on to show him this technique by coating his hand and making a thrust which damages the enemy WITHOUT TOUCHING THEM. So obviously it is the haki which is thrust from the palm to damage the opponent. This is the same type of Haki application Sentomaru used to attack Luffy preskip. Sentomaru's thrust was so strong that it sent Luffy flying several meters away it implies that the strength of thrust is also important.
So now explain to me how that is different from Zoro sending a haki flying slash out of his sword to cut a logia like monet or what happened in the spoiler as shown? Obviously there's no difference as all deal with projecting haki outward through the air to attack an opponent.
A further advanced form of this is what Luffy has demonstrated here with the tree which again shows he is not actually touching the object.
There's no going around this, there is ample evidence
Since when did I say that Luffy is was touching them directly with his fists? Youโre right about this not needing to be debated, though, but youโre wrong on the comparison.
When Luffy attacks something with his new CoA, the haki is not flying away from his body. That was shown in the drawing. When Rayleigh uses the barrier haki on the elephant, haki was not flying away from his body. When Sentomaru used the barrier against Luffy, haki was not sent flying away from his body. Hyou explained the concept before Luffy accidentally used a stronger form of haki. The barrier does not get sent away from the person.
This is not the same as Zoro sending a slash. The slash gets sent flying away from his person. Heโs not doing the same thing as Luffy.
Luffy throws a punch and the haki stays around his fist. It never leaves the vicinity of his fist. Itโs not a shockwave. Heโs just punching really fast, the same as heโs always done. Heโs not sending a haki shockwave, heโs throwing a punch and then drawing it back.
