Of course not, unless it becomes mainstream, crypto usage will always be by early adopters and technologists. I don't care if you accept cards as well, I just want to be able to pay privately with Monero.

You're right that for chargebacks specifically the only way to eliminate them would be 100% crypto, not the option of card and crypto together, which is significantly more likely. But there are other benefits for customers(privacy), which is why I use it.
