Technically this is true but it makes a lot of sense by creating an analogous experience as with retail.
If I walk to the corner store to pick up something I’m not paying a line item for the logistics that delivered that item from a factory in China, nor a line item for the rent to keep that item sitting on a shelf in walking distance. I just pay the price of the item, and those costs are baked in.
Maybe an economist can argue this isn’t the most efficient way of paying for externalities but it’s hard to argue it’s without reason. It’s clearly a preferred consumer experience. Amazon prime is like a Costco membership. The only difference is Amazon handles last mile from the fulfillment center, Costco expects me to provide last mile fulfillment with my car.
