I dont think its an undue burden to require retailers to verify things like safety certifications. Yes, it might make it impractical to have a company sell billions of different products, but I'd argue thats a good thing. You might say "well, sellers will just counterfeit the certifications", but the fact of the matter is courts tend to look at actions, intentions, and motivations, they dont interpret laws like computers interpret code. The fact that Amazon co-mingles inventory and seemingly has near-zero interest in getting involved in their own supply chain means there is a lot of low hanging fruit that is being ignored in the interest of profits. Changing the law would a step in the right direction, even if imperfect.
