So specifically on addressing fraud, this only helps the merchant. You could make an argument that decreased fraud decreases costs but human greed overtakes that assumption. So then what’s left from the consumer side? What if the merchant send you a bad product? They have no incentive to make it right. You could argue that eventually it will put them out of business from bad reviews however this doesn’t always work in practice and you’re still out of your money for the original bad product. With a centralized system we can just reach in their account and take it, refunding you your money and costing the merchant more in the long run, further making them want to do legit business. This permanent contract you speak of is a double edged sword that cuts the consumer more than the merchant.
