So your argument is that any comic book based show can create whatever it wants, whenever it wants, with no in world or inuniverse explanation. One day we could just have an area in New York where gravity doesn't work correctly, people just walk through this area of 1/4 normal gravity....but no need to explain that, viewers will have no issues, its just a comic book after all.
That's a TERRIBLE basis for a narrative model. Its also anti-theatical to the pillar by which Marvel is based. What set Marvel apart from DC in the first place was it used "real places" like New York. The idea was that these were people and places that could actually exist, and then we thrown on the crazy comic book stuff. But that means you are still starting from a basis of real world realism. Everything is like it is in the real world....until you apply the comic book stuff. But if your going to add in the comic book stuff, you have to state that.
Now, I don't have a fundamental issue with the idea of making someone stateless, if that's one of the curveballs of the MCU wants to add in. Just....explain it to me. Have someone ask "so remove his citizenship, so Fisk won't have a country?" and some one responds "exactly that, no country, no home. Its a rare option but after the the 'insert law that doesn't exist in the real world' was passed, its an option for these extreme cases.
Ok so that's a new narrative weapon in the MCU, fine, got it....we move on. Rather than a bunch of us speculating because we don't even understand what you actually did in the story.
