Honestly why not. They also fool with the idea that some system in their castle runs automatic when it's actually slaves from underneath that make it work, makimg the so advanced kingdom the reverse of what it was.
I am also starting to believe more it wasm't a simple Ancient Kingdom good, 20 Nations bad. Eith Vegapunk saying thay theory is a conjecture for now, and Rayleigh saying the straw hats might reach a different conclusions
- 20 nations alliance was a lie, there's a ruler over them
- Even then an advanced kingdom more than Egghead with the implications of thrm being creators of df, ancient weapons, allies like giants, wano, lunarians. D clan probably lived in ancient kingdom
- I think Teach's ancestor took over the ancient kingdom from with in, ans the world legitimately feared them for misusing power. Probably even Joyboy made the alliance and beat them, but of course there were those with ill intent like Imu, but too less info on him other than someone might have perfotmed immortailty surgery and that he may have Uranus, who may have stolen shit from the defeated ancient kingdom and striked Joyboy.
