Exactly. This video stupid. He even agreed that there is a need for a form of verification that the refurbished product meets quality requirements.

Rating/Reviews can be manipulated. Especially on amazon - a platform where resellers can get away with shipping rip off producs link. Since Apple doesn't want to handpick the authorized resellers they use a financial hurdle... Not guaranteed to work, but neither are customer reviews.

Besides, I kinda doubt that small resellers have too much inventory that they can't sell on other platforms/their own shop. If they can't, it creates an opportunity for a 3rd party to collaborate with the smaller but quality shops. It's not like the demand for high quality refurbished products will diminish - now that apple again rised it's prices.
