I can't say I agree with that logic of yours. "All entertainment is pornography" is such a large arse statement that I won't even touch it...
* This has a negative score because it's easy to see that the MC is a childish moron, and nobody likes him. Giving ultimate power to a moronic child does not seem like a fun story to go through. If the MC actually deserved his capabilities, even if he was overly OP, it'd be much more acceptable.
* OPMCs are not a problem, even from chapter 1. There are so many "slow life" OPMC stories out there and none of them are a problem to read through. The issue is the writing capabilities of the author, and this one is on the level of a gradeschooler.
* Your analogy to One Punch Man is just bad. The main focus draws almost instantly away from the MC, and his amazing mighty powers. Most of the narrative focuses on other people, who are around the MC. As such, every reason you wrote as to why OPM works is completely irrelevant. OPM works because of the world and characters that exist around a living deus-ex-machina, that try to solve problems like a human with certain limitations would, while OPM just solves everything immediately when needed. Read the manga again, and notice how the MC almost never appears in his own story.
* This is more of a personal rant, but Konosuba works because the "MC didn't collect every single women in the world, and he's not OP"?
The MC is a punching bad of the author, his sole existence is to be surrounded by complete incompetent idiots for him to react to. Konosuba works because it's a very basic form of comedy, in which you bully someone and they "react" to it.
If you feel like you sympathize with the MC, that's on you. I'm not saying you're wrong here, you feel how you feel, but "Konosuba works because the MC is not OP"? I wouldn't say that.
* I'd be much more on board with this mango, if the MC was not an insufferable teenager.
Welp, that's my 5 minutes of rants.
