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.
You have this balla, this shot calla, and he's got 20 inch blades on his impala. Why the FRICK would you make him a jobber so quickly? It was IMMEDIATELY obvious that he was nothing but fodder for the REAL villain from the moment he first appeared. Why not try to make it seem like he's an existential threat to the universe and then bring out Buu as a swerve?
What would happen if you used the SDBs to wish for every single timeline to merge into one?

Why make him weaker than Cell? Toriyama is the literal god of the dragon ball universe, able to do whatever he wants whenever he wants. So why not make better use of a unique and memorable foe?

He's a straightforward character like Raditz. He came in, manipulated Goku, Bejita, and Gohan, easily revived Buu, and got his comeuppance. He didn't need to be in the Buu arc any longer than that, especially considering how bloated the arc is already. The REAL question is why they didn't bring him back later. Toriyama clearly likes him, and Toei has been using him in Heroes for a while. It would be a much more interesting choice than Frieza, 17, or Buu.
