I know, but i'm saying that in the scanlation, Luffy is referring to all their attacks being ineffective, not just his own
Once again, it's to highlight Luffy's never give up attitude. We're talking about someone who attacked the 3 logia admirals preskip when he couldn't use haki, in an attempt to get past them and save Ace. And even without haki, fighting 2 yonko with 5 fighters is better than fighting them with just 4 fighters. It gives them a supplementary support advantage while at the same time, wasting more time for his haki to come back
As stated, there was no use of G4. In the panel before we see Luffy sent crashing, he is in base, and while coming out of the rubble he is in base
With Oda showing Luffy charging at them with a gomu gomu attack once again in base, and being sent flying once again
It's to show what Luffy had been doing during that time
Which only leads to 2 conclusions. Either his haki didn't come back yet, or he is reserving G4 for later, but i'd favor the former due to the circumstances.

In kuri g4 got one shot doing no damage.
He trained for 2 weeks just to be able to hurt kaido.
