A good point about why you care about not allowing dupes, but you can lose hours of gameplay with a rollback[1]. There isn't a periodic save. This can happen for something as benign as a player taking a lunch break and not babying their switch. Which harms the long term experience as if it happens to you once, it makes you paranoid about taking a longer term trip to a friend's island and doing something other than a short tour.
