Early in the film we see Godzilla fight some Titan on the streets of Rome. Rather than absolute panic (though there is still terror in the streets from people running away from the giant lizard), the government officials and military seem prepared and ready to roll. This is far from the same disorganized, unprepared Monarch we saw recently in the TV show and was powerless to stop the Titans. Here we see Monarch already working with organizations and armies on standby around the world prepared for when Godzilla fights a new monster.
Granted, they don’t really do anything. The humans are there mostly for show. Still, it does illustrate how much the world has grown used to Godzilla and his whims that they no longer try to stop him if, say, he decides to use the Roman Colosseum as his little bed not once, but twice in the film. It turns out the King of the Monsters is as obsessed with the Roman Empire as men on the internet. Unlike men on the internet, Godzilla can simply show up and demand to be left alone for a private tour (or nap) at the Colosseum and the entire country has to simply accept it as fact or face its potential destruction.
“Jurassic World: Dominion” promised to show how a world changes and becomes used to having dinosaurs roaming around amongst people, but instead it quickly devolves into just another park on a remote location (and also a random and terrible tale about locusts). “Godzilla X Kong” shows how humans simply accepted their role as ants and welcomed their Titan overlords, letting them crash on historical monuments whenever they want and just play support for them when the time comes.
