Cash is still an extremely common and well-accepted method of payment for brick and mortar stores, despite the fact that it (like Bitcoin) doesn't have all the consumer protection features of credit cards.
The context of the discussion was a bitcoin card vs a credit card. Cash has nothing to do with the conversation we're having. Don't move the goalposts.
But I'll play the moving-the-goalpost game. For in-person transactions they have some similarities. They both have no chargeback or consumer protections, but we're receiving goods immediately so thats not a very large issue. Cash is instantaneous, unlike Bitcoin. Cash doesn't have exchange risk. Cash doesn't have transaction fees, while Bitcoin does. So cash is actually superior for an in-person transaction.
If I'm going to do an in-person transaction and am not going to use my card, why would I not use cash? If I don't want to carry cash, why would I not use my card? And if its an online transaction, then chargebacks are definitely something I want, even with a trusted merchant. So whats the use case for bitcoin? The OP proposed one use case; I assume that there are people who find that valid. It is not a case that interests me, personally, and that prompted my response.
