Many European countries had online banking in the 80s. Largely because banks were focused on efficiency, and they wanted to replace checks with wire transfers and domestic debit cards. In order to do that, they had to make wire transfers as convenient as possible.
When online shopping first appeared, wire transfers were the obvious form of payment. Few people had credit cards, because most shops didn't accept them. And shops didn't accept them, because they were too expensive.
(When I got a credit card in the early 2000s, one of the things they emphasized in the marketing was that you could withdraw money from foreign ATMs. And you usually got a better rate than by exchanging cash. It's kind of funny that you are not supposed to use an American credit card for that.)
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.
