It seems like Toriyama is taking this arc to fix DBZ's world-building problems. Think about it, Freeza was presented as the emperor of the universe in Z, but we never really saw how the universe functioned outside of the Freeza force. After Freeza's death, power levels skyrocketed to the point where aliens in space could no longer challenge the heroes unless they were ancient evils (ie. Moro, Buu), an isolated prodigy in the middle of nowhere (Broly) or come from another universe entirely where lore is different. Notice how every alien that has been introduced from the Namek arc onwards still follows Namek arc powerlevels - Tagoma and Shisami were compared to Zarbon and Dodoria, Jaco was compared to the Saiyans, Vegeta said Trunks could defeat the Saganbo gang all by himself and they only got that strong because of Moro's magic, Paragus had a power level in the 4000s, so on.
This arc instead functions as a soft reboot of sorts. Freeza is back as emperor of the universe, but now with a much, much higher power level in the God tiers, which gives some credibility to the idea that random aliens in the universe under his rule could get somewhere near as well. The lore is developed as well, as after Freeza's death we saw that competing factions (Goichi's army, Elec's gang) took different spots in the universe competing for power, meanwhile, bounty hunters (Granolah, Soshiru) came to be as the universe in chaos was now being taken advantage of by bandits (Saganbo gang) which the galactic patrol struggled to take down. At the same time, not only is it believable that the power scale of the universe has widened because Freeza got much stronger himself, but it's also believable because we can expect the universe to have moved on from Namek's power levels already just like Goku and the others have.

How the Dragon Team would react to the Russian invasion Goku : "Don't worry guys, I've fought the Red Ribbon Army before. I've seen Dr Gero, Putin doesn't stand a chance". Shoots Kamehameha at russian soldier, snapping his spine.
Vegeta: "This looks like a job for me" "not so fast!!!" says Krillin. "These aren't just your everyday criminal. These are russian soldiers, I've seen them use their bow. You're gonna need more than your Super Saiyan Blue form" "You're sure about that?" Vegeta says, hitting Sergey Lavrov with Big Bang Attack.
Gohan: Enters NATO headquarters Head of NATO: "Please, save us Gohan, we can give you anything you need" BW: "I only need one thing" NATO: "What is it?" BW: "Courage. Oh, and a couple of Senzu beans if you can spare some" she wisecracks.
Cell: "I know what it's like to avoid the world for all these years like you avoided Russia president Zelensky" This is followed by a thunderous roar as tens of thousands of Cell Juniors converge on the ukranian border.
Yamcha: Enters the Kremlin through a window from the top of St.Basil's cathedral, swooping into president Putin's office. "Sorry for Putin ya into this sticky situation Mr president" Yamcha says, tying Putin with a rope stuck to the chair of his Kremlin office. Putin breaks free as Yamcha let's his guard down.
Hercule : "Remind me to not invite you to the next mission, kid." Buu: "BUU DESTROY PUTIN" he yells, running right through the Kremlin wall. As Putin tries to flee , he picks up Putin by his shirt collar. "Nice army, Vlad, but what you failed to consider is that we have Buu" Iron Man says. The Z team steps in to aid the citizens of Kyiv, to the cheers of the entire world.
