That is authorising the transaction and it makes sense for the card issuer to handle that. It's proving that it's "you" using the card and you really intended to pay for that thing. Maybe they SMS 2FA you, maybe they have a biometric check, etc. All cool.

The case where you have a dispute with the merchant (i.e transaction is authorised but problem is 1 layer up - you feel that reality doesn't match up with the payment record!) is different. You paid as intended but the thing you wanted didn't happen. Right now things are bundled together.

Sometimes this is handled by marketplace (think amazon, vs paypal/ebay and their different balances of favouring merchant vs consumer) but overall (e.g. consider shopify who are basically uncontactable in case of merchant disputes) I don't think the whole payments system makes this very clear. In practice it is sort of a shifting balance between various parties.

There are actually big questions of who eats risk between consumer, platform, merchant and various payment processors for a given transaction and things are a bit obscured. In practice all the parties EXCEPT the consumer know what is really going on.

It could be made much more clear who has the responsibility for resolving merchant disputes and their records could be made public, and this could be a more explicit point of difference in payment / marketplace offerings.

I think lots of people would make different decisions about where and how they bought things if they could see statistics about how disputes are handled.

I am not arguing for any specific method of solving disputes or more government intervention in general, I just think that if things were more transparent (mandatory reporting) fewer people would feel ripped off, people could make more informed decisions, and marketplaces / processors who are adept at resolving disputes would be rewarded as they deserve. Basically, the market would work better.

P.S. There are a LOT of details in this specific idea, some consumers are bad actors and are never happy, some merchants likewise are bad actors. Resolving these issues without disclosing sensitive information is extremely difficult. But largely processors are sort of punting on it in various ways when common sense resolutions seem possible. Like if a consumer has 50k transactions with 0 chargebacks and they initiate a chargeback, it's probably a merchant problem. This argues for collapsing the layers but channel-specific resolutions have the advantage of being able to look for delivery signals and other specific mechanisms of performance. Figuring who is right in the world is a hard problem in general. Possibly the Stripe Elite will correct me here since this is the Hard Problem of payments. Which can be solved well enough with statistics. Payments has a whole lot of Hard Problems which seem easy at first, it's a great area.

Now you are just confusing consumer protection with having a secure online payment system, which credit cards are not and never will be. The entire "transaction approval" shtick is just a bandaid for passing a static password around in clear text, your credit card info.

Consumer protection deals with chargebacks after the payment was made and the products/services are not delivered to required standards. This gives enormous power to credit card companies against merchants and enables obscene rent extraction against consumers who don't require it, yet still pay 2-4% more on everything they buy, even with other payment methods.
