I think this would actually, in the long term be good for Amazon. If it forces them to clean up their third party sellers and co-mingling of inventory and verify supply chains better, I would be more comfortable buying high value items from them.
Right now as it stands, for high value items or items where counterfeits are dangerous (think chargers) I have been either ordering at brick and mortar stores (Walmart, BestBuy) or direct from the manufacturer (Apple, Anker, etc)
My safety is worth a few extra dollars, a short trip to the store, or a few days wait on shipping.
For items they have in stock, BestBuy is much faster than Amazon - you can even order curbside pickup where you just drive to the store and they give you the item without you even having to get out of the car. Of course, it depends on how far you are from closest BestBuy - I have one in 5 mins drive, so I can get my stuff within half an hour if I'm lucky. Of course, the choice is less than Amazon but for things that they do have I've found them very useful. I thought Amazon would drive them out of business but now I think they have their place and I hope they stay.
When I needed new brush heads for my electric toothbrush. I hesitated before buying from Amazon, because I can't be sure that the toothbrush manufacturer-branded refills there are genuine. Going with a generic, compatible refill with good reviews is preferable in this case, aside from the lower price, because presumably no one will counterfeit it.
(I ended up buying the manufacturer-branded refill ... from Best Buy, not Amazon.)
