I don't understand the relationship between a made up scenario about a gucci bag and my comment.
Problem # 1 is the cost of returning an item and chargebacks is very high. I (and hopefully many others) are willing to pay a premium to a vendor that performs quality checks on their vendors. It's the whole reason premium brands exist.
Problem # 2 is there exist many items which consumers are not able to easily determine the legitimacy of, for example USB wall outlet AC adapters or batteries and many other small consumer electronic items where inferior parts can be used but are indiscernible to most people.
