People love to tout the beauty of chargebacks but the fact is that for a lot of business to consumer ecommerce, the buyer has a lower risk profile than the seller. It's the buyer who knows he is dealing with Amazon. The seller hasn't a clue who he is dealing with. Are the odds that Amazon will take your payment, not ship a product and say FU, or are the odds a buyer will do that, either with his own creditcard or stolen credentials?
Obviously there are exceptions here. But to me it makes a lot more sense to have no chargebacks inherently. That way businesses are protected from chargeback fraud, and as there is less fraud, payment processors have fewer losses as do merchants, which positively influences pricing both of products and creditcards in a small manner (say 1%).
Does a user still want the ability to chargeback? Fine, but it'll cost 1% in costs, from which fraudulent cases are paid for. And it's only possible if the merchant accepts it. Why is it so crazy for a merchant to be able to say 'no chargebacks possible if you use your card with me'? Of course, if it's a new kid on the block in a shady location with a weird website and no phone number, he's not allowed by the payment processor to disable chargebacks, and customers will avoid him anyway. But if he's a large retailer like Amazon, or a vetted SME like these guys with a business registration, phone number, a track record, hell perhaps even a surety bond if necessary, do you really want to force them to expose themselves to chargeback fraud or not take payments at all?
That seems pretty obvious. They still accept wire, without chargeback risks. And customers still use them. In other words, there's a market for easy and fast payment processing without chargeback protection both from the merchant and consumer side, that's faster and easier than wiring money. In the Netherlands for example we have this, it's called iDeal, wiring money that arrives seconds later without chargeback fraud, cheap and fast. Internationally the equivalent is using bitcoin with a USD wallet at e.g. Circle or Bitreserve by the founders of ColdFusion and CNET respectively.
Don't get me wrong, chargeback protection has its place. But payment processing without it, does, too.
