And here´s why the parody indeed hinges on his power´s origins: The current "explanation" is so ridiculous that having him be unmatched can never be contested. Never! He didn´t do anything special to become stronger than everybody else, so how can there ever be someone of equal or greater power? I´m sure most of the other heroes did A LOT more training for the entirety of their lives, yet are vastly inferior to Saitama. No matter what kind of strong monster or alien or whatever is introduced, there is currently nothing to make the assumption that Saitama would be outclassed/have troubles in a fight. Because his power´s origin is untouchable. They could have as well said "well, I never did any sports. One day I decided to lift a 10kg bell bar for 10 minutes and that´s how I became this strong". It´d be the same result. His power´s origin is so ludicrous that him being "unmatched", as you say, can never be put in question. Because there is no tangible basis on which to overpower him. And that´s why his power´s origins are the single parodic element.

If you disagree, please site specific instances (like I said, excluding Genos) that invalidate the parody aspect of the show if you change Saitama's power origin.
You can take ANY scene you want. If Saitama´s powers had a proper origin, then there could be a real plot. Like an evil organization secretly studying Saitama (akin to Lex Luthor stuyding Superman). There could be aliens from outer space with similiar powers. There could be others who undergo the same training as him. Etc etc. Having a proper explanation would make his power tangible, if not attainable. For pete´s sake, a simple power scouter-device like Vegeta used to wear would let the bad guys know what they´re in for. But you´ll never see a scouter, because the show would never reveal Saitama´s limits (as of now, at least).
