Nah bro, that's not how it works.
Each verse has its own rules of powerlevel scaling but they're inverse exclusive, hence you cannot equate One Piece's Douriki PL scaling to Dragon Ball just as you cannot equate Nanatsu no Taizai's to One Piece either. I mean, look at Lucci's Douriki, didn't he have 4000? Well, this character is town level/city level in AP at best, meanwhile DB characters around ~400 are small planetary-ish.
Where is the exact issue? Upon a blink of a moment, when Gohan's rage reaches its peak, his PL rises very exponentially, to which he's suddenly a clear danger to opponents stronger than Goku and Co. That's also the reason why Gohan managed to injure Nappa despite stronger Z fighters dealing jackshit to him.
Also, Gohan's rage was an essential plot element when fighting Cell. Making Gohan angry was Goku's plan to defeat Cell once and for all.
Why?
Don't get me wrong, this composite version would murk everyone in One Piece but such stats are just additional good bonuses in crossover battles. Heck, there are much more haxed characters in which planetary/stellar AP and durability stats are basically irrelevant since these characters are so broken, they automatically neg such opponents with their abilities anyway.
As for now, there's no proof a version like this is a moon buster as well.
Gohan injured Raditz because he - at this certain situation - got such a ridiculously high PL, his got close to Raditz' (1500). Also, don't forget that Goku and Piccolo can rise their powerlevel when powering themselves up for a higher end KI attack (in this case, Kamehameha or Piccolo's Makankosappo) and only in this shape, they can injure Raditz as well.
Therefore, it actually means a lot that Gohan's base PL was this high, if he actually powered himself up, using a high level KI attack, he would pulverize Raditz.
It's actually quite simple: It's because Gohan's attack > Goku's and Piccolo's KI blasts bar Makankosappo in Attack Potency. If Gohan were about to charge directly towards Goku's Kamehameha, he would overpower the blast actually.
Its energy has levels of planetary destructive capacities indeed.
Another question, is this attack NOT planetary stellar levelled?
I mean, the AOE of this attack is very centered and focused on a certain physical shape but it doesn't mean it has no chance against Saiyan Saga Vegeta's Galick Gun which would have obliterated the planet.
No, there's no basis to it.
