Despite being a trail blazer on checkout free stores, Amazon may go even further at some point towards a "sample store" shopping model predicted by Edward Belamy in 1887 in his book "Looking backward: 2000 to 1887" which I tried to summarise in https://peter-wurmsdobler.medium.com/looking-backward-2000-1887-by-edward-belamy-selected-quotes-4afae7ea7f39 , see section "Distribution of Goods".
Further abstraction leaves in essence three categories of items to be procured: 1) products we want to buy any instance of (repeat purchase), 2) those we want to touch but buy a copy of (sample store), and 3) those we want to see and buy the very item (food market). https://peter-wurmsdobler.medium.com/reducing-resource-expenditure-for-the-procurement-of-household-goods-e9851474d8db tries to explain that and I would be interested reading your thoughts.
