Not at all. There are other solutions around the world that bypass the payment gateways and credit card acquirers. In Holland they have iDEAL, in Thailand they have QR Codes, in Australia they have BPAY and in China they have WeChat Pay. There are tons more around the world. As a merchant, it can be very expensive integrating directly with all the different options, which is where these companies help - for a fee. If you want to maximise sales and minimise abandoned baskets, you’d better make it easy for your customers to pay using the method they prefer!

Do those services also deal with fraud, chargebacks, etc., or are they basically digital cash equivalents?

I thought chargebacks were generally considered a pain: for merchants because it's used by abusive customers, and by customers because it means the merchant (or rather, their payment provider) needs to play a guessing game about whether you're going to do a chargeback and may baselessly deny you the purchase, as well as increasing the cost for everyone due to this increased risk the merchant has

Or maybe it's just me but I greatly prefer the non-algorithmic non-pay-on-credit mechanism where I simply pay for my purchase and the other party has no reason not to take my money (and the bank no reason not to issue the payment method to everyone: as an EU foreigner in Germany without pre-existing German credit score, getting a card at all was a pain, no matter if I could guarantee it with some insane deposit amount... I have the money, they just didn't want to issue a number to pay with because of algorithm magic). Now that I got that card number by co-guaranteeing with a German, purchases often fail like when I use mobile data which is from a Dutch phone number and so it looks foreign and I guess smells like non-standard situation → must be fraud, let's deny the purchase

Digital replacements for cash, like the aforementioned iDeal system, just always works and is available to everyone with a bank account in the Netherlands (iirc they're looking to start using it EU-wide because the costs are so low). No need to pre-pay either (like with paypal credit) because it just draws from your regular account. Another advantage is that it is owned by the banks collectively so you're not giving a ton of information to a third party, like most German-native payment options requiring to verify a phone number before you're allowed to pay the merchant for absolutely no reason other than tracking

The brazilian PIX is a digital cash transfer from bank account to account built by our central bank. It doesn't handle fraud and chargebacks which must be done by the seller or third parties.

There are countless systems and they all answer that question differently.

If the systems are local to a specific country, they could reasonably skip the idea of chargebacks and just rely on the legal system to resolve any disputes?

iDEAL in the Netherlands is an instant credit from your account directly into the receivers. The KYC part has already been handled by your bank.
