Luffy hasn't been able to go up against non-mooks in the New World without activating some sort of Gear. Plus, it's not confirmed that the Vinsmokes can only fight with their raid suits, but weren't strong enough to break out of the BM Pirates' ambush without them. If someone has a main weapon or Devil Fruit they use to a great degree, they'll be greatly weakened without it, and the same holds true with the Vinsmokes.

There are currently two Sweet Commanders out and about - and Oda hasn't done anything with Smoothie, but he's not the kind of writer who would suddenly make her weak and easily defeated. It took Luffy 11 hours and help from Nami and the homies she controlled to defeat one of them. The one considered to be the lowest threat by the World Government. Even if he fights on par with one Sweet Commander, who gets the other one? Sanji was struggling with Daifuku, who is one of the stronger members but isn't a Sweet Commander. So I doubt he can take on multiple strong members, let alone a Sweet Commander. Jinbe wouldn't take on one solo because why would Oda portray him as having equal strength to Luffy?

Big Mom has demonstrated that her crew isn't particularly cannon fodder. In addition to the Ministers, which we've yet to see dozens of, she also has her chess-themed combatants like Tamago, whom I'm sure are in the venue as well. Jinbe tried to take on a bunch of guys who seemingly looked like mooks, but was quickly overwhelmed. A few more people on the Straw Hats' side aren't gonna solve that. These guys aren't patsies; they have Devil Fruit powers and know how to use them in conjunction with each other, as they demonstrated against Luffy in their battle. Even though Luffy was injured, I don't really see how much he could've done in that fight even if they were healthy. When Monty puts you in a book illusion it's pretty much over.

And of course, there's Big Mom herself. Her screaming is definitely more extreme than before due to the magnitude of the portrait's destruction, but it was temporary before and it'll be temporary now. Once she regains her composure...who's gonna be lucky enough to confront her?
