You don't reverse it. It's like a cash transaction in the sense that it's irrevocable, which means people understand it intuitively. But unlike cash, there is an effectively permanent record of the transaction, connected to the participants' legal identities. That tends to discourage scammers. And it all happens within a single jurisdiction.
This is not true, you can reverse SEPA transfers via your bank. You do need a reason though and there are time limits but if a seller just runs away with your money you don't have to go through the courts in the general case.
