I mean, I can’t even argue against that. Some people find some forms of work fulfilling, and even switch to games because their own jobs don’t actually give them that feeling of fulfillment.
Monster Hunter is a prime example of a game that sets such elongated goals that it’s regarded as a “grind-heavy” game - but its players like the grind. Heck, the entire space simulator genre often involves quite a lot of “Space Truck Simulator” gameplay, where you’re just engineering good ways to ferry cargo around.
Which is not to say that’s what Starfield aims for. From what I’ve played, it’s closer to Sea of Thieves, having adventurous interruptions - where you start a boring, routine mission to bring Sugar from one merchant post to another, but then get ambushed by a skeleton ship, then a giant shark, then find a map to a buried treasure nearby.
