It’s a hugely onerous task because it requires mapping every listing to a known product.
If someone sells a “green couch” then how do you track recalls for that?
You either force everyone selling anything to look it up in a big database you maintain and disallow generic sales, or everyone is just going to list things generically anyway to avoid the hassle.
It’s an idea that sounds easy when you assume everyone’s making perfectly formed listing, but sounds like a waste of time when you look at real listings.
EDIT: Replaced high chair example with a couch because people were pointing out that a high chair listing would be deleted. Though that proves my point, that any item covered by regulations wouldn’t be allowed on the platform, so if you extend regulations to cover every product ever made then you can forget about being able to buy things second hand. I’m guessing Amazon would actually love that, but you wouldn’t.
