"Have you ever had and experience that disproves it?"
Yes. Prey: Mooncrash. I hated it in the beginning, but it grew on me and I ended up loving it. It was basically developers saying: "We get it, but trust us, we want you to be able to experience the simulation in its whole glory. Just give it a go." And they were right, that Prey DLC is superb. I learned that stepping out of my bubble to experience something slightly different can be very rewarding and made me appreciate developer's efforts even more. I'd probably savescum my way through it, but in Mooncrash, dealing with consequences of your failures is more fun / challenge, and without quick reloads you get to see how simulation can respond to it, often with unpredictable and hilarious ways. It's sometimes unfair because of that randomness, but oh boy, it's also super interesting and rewarding, when you actually finish your run by the skin of your teeth.
Also, I like checkpoint saves in games, it's an art of its own in game design. When I don't have to think about saving at all, because automatic checkpoints handle it for me in seamless and unobtrusive manner, so I can focus on playing – that's the best scenario for me
Btw. there's a whole separate topic in psychology of games related to saving systems. LGS / Ion Storm's Randy Smith made a presentation on compulsive saving / loading, "How to help players stop saving all the time" – something like that I can share it with anyone interested.
