Because in some respects the original ghost in the shell was saying something about these nations. The entire significance of the back end political theater is a bit meaningless if the places talked about are abstract considering it has to do with one nation faking a terrorist attack in order to perpetuate a war against another nation. This isn’t even touching how, in the world of GitS, the United States is supposed to be a tyrannical empire on the quest of taking over the entire Americas and a bit of a malicious ally to Japan. Gee, I wonder why they censored that. 🤔

The goal Science Saru had was to adapt the manga as is. The censorship of it, unfortunately, has undermined the goal. I still enjoyed it but I hope that an eventual blu ray release untainted hy Amazon restores the intended names. It really hurts the world building of the original GitS which, yes had plenty of fake names, but did try to ground those fake names as evolutions of existing nation states.
