How do countries like India and Brazil do it then if it's so hard and challenging that it couldn't possibly be a public service?

What india and brazil have is more equivalent to Zelle in the US, not visa/mastercard. There's no viable chargeback, no international interoperability and no fraud protections.

Chargebacks and fraud protection are largely needed in the credit/debit card system because you go around handing people the key to your safe to merchants and ask them to take whatever they want. And pinky promise not to share the key with anyone else.

Once you have sane system like pix or upi, there is far less need for chargebacks and frauds.

		Fraud protection in this case doesn't mean protection against having your card copied, it means protection when you've made a purchase and didn't receive the product you were promised. Which payment method would you prefer to use for an online purchase: One where you have no chance of getting your money back if it turned out to be a scam, or one where you have protection against this?
