Because mastercard/visa don't personally bear any risk they are very happy to process refunds and chargebacks in the customer's favor. It's not a perfect system, but it's much better than direct bank debit where the customer has very little recourse. There is also a significant privacy issue. Today my bank can only see the sum total of my credit card purchases but not what I buy and from which vendor. Amex can see what I purchase but knows very little about me otherwise. I like this separation, and I like that it's hard for the government to get a complete picture of my financial affairs. I know credit cards get a lot of hate (here and elsewhere) but as a consumer I think they're exceptionally convenient.

That’s not how chargebacks and refunds work. Mastercard and Visa are not involved in the vast majority of disputes at all, it’s entirely handled by the card issuer and card acquirer. Mastercard/Visa only get involved in cases where network party has broken one of the technical rules of the network. For cases of missing or faulty goods etc, Mastercard/Visa do nothing except transport the messages used by bank/merchant to litigate the dispute.
When Mastercard/Visa are forced to step in and make an arbitration decision, they charge a hefty fee (hundreds of dollars) to the losing side to do so. So they have no issue with people raising disputes, it makes them a lot of money.

This is naive, all banks and credit card issuers are required by law to perform KYC (Know Your Customer) to ensure they know exactly who they’re transacting with. It’s trivial for the state to buildup a complete image of your financial situation by sending a small number of court orders to banks and financial entities to turn over all their records on you. That’s ignoring the automated tax reporting that banks also have to do.
