You lack the inherent fraud, bankruptcy and other malicious actor protection that Visa/Mastercard provides.
Bought something online and didn't receive your product? With PIX you're SOL, with Visa/Mastercard you get a chargeback.
The moment you start burdening the payment processor with the roles of judge/referee over all goods and services you end up with the mess we have with CCs where Visa/Mastercard are morality czars that dictate what goods and services are valid or invalid, nuking people and companies out of modern society for their own arbitrary reasons.
Edit: And just to add, you can have "chargeback" for PIX as a separate service, most banks offer PIX insurance that is basically CC chargeback by a different name. But the key is that it is separate from the payment infrastructure itself, it is an insurance service that you contract separately. And that separation ins very important, the insurance company can't roll back transactions arbitrarily, or deny people access to the financial system, they have to pay the victim and then claw back their money in court, which is the appropriate venue to decide who is right or wrong in a transaction.
Base payment products should just do payment at operating margins rivaling a non-profit. It's public infrastructure
Outside pressure behind much of it.
In any case, there's a fundamental mismatch between pressure groups and the leverage they can exert through single-consensus. I don't know how to describe the other consensus that is on my brain, but it is distinct.
This is the reason I only _ever_ spend money on credit cards, and never use cash or debit cards (European in the US). I've personally had at least three disputes this year resolved in my favor by American Express, and will not sign up for something that suggests courts should do so instead.

Disputes between non-fraudulent entities happen of course. But I really don't like some algorithm somewhere taking seemingly arbitrary decisions on that. It usually just amounts to robbing merchants of their money, and adding some exorbitant refund fee to top it of. Settling disputes is what small claims court and dispute committees are for.
Of course, with iDeal now effectively becoming EU-wide, things may get more difficult.
Which makes it somewhat less than iDeal for anyone who isn't Dutch. The magic of Visa and Mastercard is they enable commerce between two people, even if they bank on different sides of the planet. Well, not Russia - but they do work in Japan, and if you ever dealt with the Japanese banking system you will know that's a minor miracle.
Which illustrates one of the most prolific examples of regulatory capture.
Credit cards became mainstream because of that protection, which was a triumph for the payment processors. Whatever they spent on lobbying was a bargain.
Visa/Mastercard aren't handling chargebacks, the banks are. With PIX the way to get a chargeback is the same: if you've been victim of fraud you open a claim with the bank, they'll review it, then possibly give you a charge back within a week. This review process might take longer or be denied, which requires a lawsuit.
But it's only less risky for banks to chargeback immediately on Visa/Mastercard because they make so much money from credit card fees that they can afford it.
Like, yes, it’s technically a bad deal. But it’s still worth the extra cost for most people
Is it? You charge back over 2% of your transaction volume? If you don't then just removing the middleman will make everyone happier. If you do, I have questions as to why...
My Brazillian bank charges me 600% yearly interest on credit card purchases.
However, the cost of a lawsuit can quickly offset the costs of a CC. Depending on the state, there may not be a maximum cap on expenses, making lawsuits incredibly expensive. (Whereas having paid by card you could ask for a chargeback instead of needing to sue)
It's also a very time consuming ordeal having to sue vendors in these instances.

There's also the different insurance plans offered by mostly all banks and payment-adjacent businesses.
It works (passably) well here as well. However there's widespread lack of basic civic awareness which makes it harder for people to even know they could be settling such things on small claims court.
This is no longer the case outside US. Last time I had the account of one of the few credit cards I'm using (on the Visa or Mastercard networks), for transactions I should have been clearly reimbursed / credited, as it used to be the case, actually awarded in my favor, was four years ago. Recent transactions, with proven vendor at fault, ended up with my loss. All over Europe (Im traveling a lot). So no tears shed for Visa or Mastercard losing the EU turf.
