I wouldn’t make a transaction online without those 2FA measures and I wouldn’t make an in person transaction without pin. I haven’t checked actually but I assume the cards can’t be used without pin/2FA e.g if the details were leaked.
I assume it's up to the e-commerce site to implement the check, and in this case it had timed out and they decided to process the order anyway.
Sure, you'll probably win any chargeback, but they don't necessarily prevent the charges in the first place.
Even if you don't, if your card details get leaked, fraudsters definitely will. You can't prevent that by shopping selectively.
Same that happened with pins 20 years ago, once all stores had them, you could no longer make a purchase with just card+signature.
What’s needed is a block for use in countries where this hasn’t happened. Not sure if that’s the case.
A geo block could theoretically work, and I know of some issuers doing just that, but it's also pretty inconvenient when traveling or shopping online.
