The original, pre-DBZ, Dragonball setting was freaking amazing for the layers of bullshit it was dripping with. And DBZ wasn't all that much of a slouch itself, even if it tended to wander out into fairly uninteresting tangents.
The story takes place on a massive, pangaea-style supercontinent... which may or may not be the only one... and a few outlying archipelagos. Its a world still reeling from the scourging of the Demon King Piccolo three hundred years ago, the survivors having mostly clustered into five cities that barely even bothered to have names: Titling themselves after the four cardinal directions they were arrayed in and then their capital 'Central'. You have to get beaten down hard to give up on even having proper names. There is so much empty there.
You have actual demons, nominally directed by Shula, periodically erupting onto the planet in what I honestly consider more of a particularly rowdy bar crawl than a proper invasion. Apparently demonic or external intrusion is prevented by the diety Annin of the Furnace of Eight Divisions. You can walk to the gate of the dead. Kami acts as planet-scale god on appointment from the bloody weird, but typical for eastern mythology, celestial bureaucracy and with the backing of an outright lovecraftian gravemind thing of all previous guardians of the earth. And that is before we get into any of the vaguely comedic bullshit.
It gets glossed over a lot, but there is some serious crazy there just from a worldbuilding standpoint.
Yeah, this in a nutshell. I've been trying to write a Goku SI since 2015 titled "To Become a Beacon of Hope" with some AU inserted in, trying to take full advantage of all the bullshit that Toriyama wrote. It's pretty much impossible. Between the post-apocalyptic setting of King Piccolo and everything else you've said, it's almost impossible to take full advantage of everything. That's without taking into account the fact that we don't even know what the event that marks year 0 of their calendar is. Or, for example, the map has some frightening similarities to post 2300 AD Chrono Trigger map. Or where exactly have all the magic users gone? Did they all get killed during the King Piccolo wars? The only one we see that isn't a martial artist is Baba, and she's OLD. Or, for example, the technological disparity between where Mutaito and Master Roshi lived and the final battle with King Piccolo, with one clearly showing an 18th century Japanese aesthetic and the other a 20th-century Western aesthetic.
The whole story of DB (not DBZ) is so full of potential to fill with extra information that Toriyama never did that you could write entire stories of those time periods.
