I feel like you didn't actually address what I was saying, this started when I pointed out that there's evidence that MHA takes place in the late 21st to very early 22nd century. I asked where people get this idea that it's hundreds of years into the future despite this evidence.
It's the far future but technology hasn't really developed at all beyond in certain niches that may or may not be Quirk backed, doesn't really answer the question of why you or anyone think that it's the far future. In fact it seems more like the lack of technological development should point to it not being very far into the future.
If we were extremely generous with the timeline and set it reasonably far back, it would still set All For One as being born in the 1950's. The architecture around him during his flashback sequences to his beginnings simply don't match up with pre-WW2 Japan at all. He also states that he envisions himself as a demon lord like character similar to the comic books he used to read with his brother in their childhood.
So we have that. We have a rough timeline for the age of One For All, also. It's gone through eight people before it reached Izuku. One of them had it for eighteen years, we know that for a fact. All Might's age isn't actually on any wiki I can find but it's pretty commonly referenced that his age of peace started about forty years prior to the start of the anime.
So about sixty years between those two. We don't know how long the other wielders had One For All beyond the general fact that the Quirk wasn't killing them and they instead passed it on before those effect began to manifest. So anywhere from five to ten years per person which is, honestly, a painfully long time to be fighting a shadow war.
So, let's err on the side of caution. Let's say that the average holder of One For All had it for five years before moving it forward. That's still six other people for a total of thirty years. That puts us at around ninety years which can fit, roughly, with the officially stated age of All For One being 100+ years old.
So, even if MHA is taking place in this century, it's doing so about forty years forward. I can't speak for everyone but the differences in my room right now that I can point at as being wildly different from twenty years ago are pretty significant. If we haven't moved forward on cellphone or T.V. technology in forty years then something truly terrible has happened.
Hence the argument that trying to figure out the year in MHA doesn't make sense.
(I want my holographic television, damnit!)
Alchemist: "I've never seen anyone use Prestidigitation like that before."
Izuku: "I've had a lot of time to think about it."
Alchemist: "Kind of cruel, really."
Izuku: "Hey, at least I didn't hurt anyone! Physically, anyway."
Alchemist: "Turning a bunch of self-conscious teenagers' clothes transparent?"
Izuku: "Everyone was too busy trying to cover themselves (ineffectually, I might add) to bother trying to get the flag!"
Alchemist: "You are a cruel, cruel boy. You've learned well."
Hagakure Toru: You made me human colored?!
Izuku: Well, I had to think of something! You were invisible before!
Hagakure Toru: Yes! And naked!
Izuku: As my teacher would say; That sounds like a you problem
thanks for the awesome chapter and for writing
You are very welcome!
While funny at first, the second thought I had was "The Grapist would absolutely love that..." And that killed all enjoyment for me.
Mineta: Oh god, I'm blind! Help! Someone! I can't see any of the beautiful ladies! In their invisible outfits!
Aizawa: Problem child, what did you do?
Izuku: It's a fun application of color changing!
Nedzu: Oh? Do tell!
Izuku: I changed his irises from transparent to black.
Aizawa: Change it back before he hurts himself.
Izuku: It'll wear off on its own.
Aizawa: When?
Izuku: When he learns his lesson.
