You know that lots of card providers can generate virtual cards for free on demand these days right? Another set of details that works the same as your original card but can be used for, say, just one site and cancelled at any time if it gets misused.

If that's your only gripe than that's probably the easier way than switching to an entirely separate financial system.

It is not realistic to generate a virtual card for each purchase. It creates a documentation headache as well, such as handling returns and payment proofs.

I expect credit cards to become more like private keys in time, managed by the company, and transactions will have unique tokens so that your real number is never passed to the vendor. Blockchain like ideas will be implemented in "TradFi" without the overhead of blockchain.
