What do you mean by “spending time working to scrape back money”? Cashback rewards are fairly automatic. Maybe some have a simple redemption step. Apple Card’s is 100% automatic.
So yes, the rewards are "automatic". But what's not "automatic" is you getting the maximum possible reward percentage on your spending. For that, you often need to optimize your spending along the guardrails put up by some random card issuer. Which takes effort and time. I don't know about you, but I've got better uses for my time, so I'd prefer just not having 2-3% of the price of all products I buy to go towards obscure rewards through which I need to claw back some of those 2-3% by gaming the system. If I want to play games, I buy a computer game and play that.
