Well, there aren't many sellers which try to directly sue their allegedly cheating customers. It's almost never worth it. Platforms might be able to make that work, but they don't do that either. IMHO, the desire for buyer info is not motivated by trying to hedge against customer fraud but on trying to monetize everything - selling data, advertising to existing customers since they're more likely to buy v2 of what they bought, etc. Giving less of my info to sellers is therefore less a technological characteristic of a payment system, and more a choice by the system's creators. There's no technological hurdle to even having a credit card which gives a bit less info. Theoretically, the credit company only needs to see my expense, current available funds and some transaction/merchant identifier, not exactly what I spend it on or even who I am. I'm hoping some of the new NFC-based payment systems will make privacy a differentiator. They'll need something if they want to get into the market with such established players. We'll see what Apple comes along with. I've been slagging them quite a bit, but they do try to make privacy a selling point. Perhaps here too? As for the second issue, I am sure that a form of chargeback could be implemented on top of crypto. Your first link just shows one way to do it - but doesn't link to any implementations of this. The second link explicitly mentions 'no chargebacks', so again, it's theoretical in the sense of not existing. The hurdle here is again not technological, but the apparently inability of the crypto community to think that people might want this behaviour. Sometimes even sellers. Where I live, allowing return of unused goods before a certain period of time has passed is mandated by law. Payment methods which does not have chargeback may actually complicate seller's business in this case, since than they have to be even more careful against internal fraud and pay an extra fee for the return as if it were a new transfer (if not in cash). Thirdly, fraud and ransomware are getting worse and worse. I'm sure eventually there'll a crackdown. I just can't predict how, where and when. But crypto would be a very convenient target politically; this doesn't yet require targeting any large stakeholder. Alas, the one thing the crypto community is right about, is that many economists are just waiting to be able to implement negative interest rates - but I doubt crypto would be able to change anything there.
