There are a lot of undesirable side effects with that solution. You shouldn't have to be tech savvy enough to host a shopping experience that's competitive with Amazon in order to sell things online. You ought to be able to focus solely on your product and if it's a good one you ought to be able to compete with Amazon Basics on a level playing field--even if it's a field served by Amazon metal. I think we need more separation between the part of Amazon that handles clicking "buy" and printing shipping labels, and the part that comes up with things for sale. So much separation, in fact, that the former considers the latter to be no more trustworthy than any other company or individual. Seller reputation should be important, and the medium for determining if a seller is trustworthy should be free from conflicts of interest. If the user facing part was adequately adversarial about the cardboard facing part it would result in a UI which had no reason to encourage the user to trust the contents of the cardboard, and instead simply presented facts that enable the user to apply their own scrutiny.
