I’m not clear on how this solves the problem. Counterfeits can be hard to detect. Counterfeit food, toiletries, and electronics can poison you or start a fire. And my redress is a generous return policy?

Amazon receives inventory directly from manufacturers. Third party sellers are significantly more likely to sell counterfeit products

Same reason you’re not likely going to find counterfeit goods on the shelves of a Target or Costco

they have a history of "comingling" goods that claim to be from the manufacturer but sometimes are not.
