I don't think he'd stop even if his ego demanded he do so at a certain point. He's a crippled man, with no real hobbies, friends, or life outside of his cooking. He'd be genuinely bored to tears. I think he enjoys the act of creating, even if we'd consider it a gross desecration. Its one of those innate human things, we like to create. Kids doodle, teens build computers and fursuits, consoomers build pop and vinyl collections, and people like Jack just post whatever they do, however bad it may be.
While I do think his ego is why he tries to present himself as some big successful e-celeb, its not what drives him to create. His ego instead explains his efforts to try to sell merch, or secure sponsorships, etc.
