You can't have atomic transactions when one half of the transaction isn't electronic.You either need to replicate the trust system that greases cash transactions, or make the "get stuff" half of the trade as easily verified as the "move money" half. The latter is the easier part of the problem, because part of the reason that money is money is the fungibility factor.
Solving the former would eliminate counterfeiting, provide record of provenance, track supply chain, simplify customs clearance, and trivialize recalls in one stroke. But it is a truly massive undertaking. Solutions like insurance and charge-backs are several orders of magnitude cheaper to implement, and don't require an unbroken chain of cooperation from everyone in a supply chain from manufacturer to consumer.
It doesn't exist. It won't exist without a lot of work. But that's what everyone wants. Right now, protecting yourself from scams in a caveat emptor marketplace is an externality that can be diffused away, such that it can be paid a little bit at a time, by everyone. If you eliminate the possibility of scamming, that's removing a cost, such that no one has to pay it any more. A payments system that cannot be scammed by anyone but a giant conspiracy of renegades, or a state-level actor, would likely be preferred by everyone.
But a weak link like Amazon prevents this. They do not themselves know whether the goods in their warehouse are counterfeit, so if you buy something, receive genuine goods, and return a counterfeit to them for a refund, they don't even know that you were the one that scammed them instead of one of their "fulfilled by Amazon" sellers. If they eliminated the common binning, and were able to show that the goods shipped to you were verified as genuine, with a record of provenance going straight back to the factory, you wouldn't be able to do that. But Amazon would rather pay the scammers than pay someone to build a scam-resistant system. That's a reasonable business decision for one company to make. Society as a whole might prefer that the scammers get a smackdown instead of a payoff.
