Honestly, if it wasn't for One Piece's world building and lore, OP powerscaling sure wouldn't rescue this manga.
If it wasn't for the lore dump at the end of this chapter, this chapter would be completely nonsensical if it comes to powerscaling. Bonney stomps on Nasujuro. Brook, Usopp and Co easily damage Saturn as well. It is one thing to be immortal but it's another one to be a glass canon. Warcury tanked a Red Roc in the previous chapter but his fellow comrade can't take a hakiless slash?
Oda can hype strawhats without dehyping the Gorosei. It's always some mega imbalance when it comes to hyping characters. Even Fairy Tail manages it better than current OP.
I didn't even look for the agenda stuff this chapter since it was obvious how it'd turn out to be. That's why I managed to enjoy the actual highlight of this chapter way more. People really have to turn their brains off when it comes to powerscaling in this manga and just look at the fights as entertainment... and the other stuff is the real fun.
