Actually nothing I said is wrong.
Lemme start with Noah.
The ship's body hasnt been touched actually, only part of the deck has been damaged, everything else, more than 90% of the ship is in perfect shape, as you can see on the screenshot. He only was targetting the deck, nothing else.
Countless hits damaging only part of the deck and stone is significantly harder than wood and golem is incomparably bigger than Noah's deck. Also, Noah didnt regenerate like Pica can.
That proves that without G4 he cant do anything significant to stone mountain and even with G4 he remains ineffective due to the nature of his attacks and Pica's regeneration. The inferior stalling game has beaten G4 Luffy and Pica who is superior at that game certainly won't lose.
