The "makes sense" idea is for low effort purchases. Simple example is itch.io. Games on there are a couple of bucks. I have my payment information saved. People link a game to me, and I'll maybe impulse buy cuz I don't have to deal with making an account or setting up payment info. It's silly, but I think it works in a certain sweet spot! But honestly I think the bigger thing than payment details is actual account creation. I'll go over to Amazon to buy a thing just to not deal with some product's bespoke checkout page, unless I really want to support the product's creator.
