Sure. If both parties are willing, you can also use pokemon cards to buy things. The main point of the comment is that it's not convenient and common to use crypto to buy goods and services yet.
The current desktop UX (today) of using cryptocurrency to order takeaway food from the market leading delivery platform in Germany is actually MORE convenient than Visa in my experience.
Visa: get card from wallet, type in number, type in CSC code.
But do they give you a significant discount for crypto vs. a credit card?
In the US you can get a 2% rebate on what you spend with a credit card. In effect, you are credited back most of the merchant fees baked into transactions.
In which case cash or crypto requires a >2% discount to break even.
Yes, I agree that it’s not common or convenient. But I think it was just a counter point that you can use Bitcoin for regular purchases and people do. And I don’t think tax law is going to stop these people.
I completely agree that the instances of use as currency is vanishingly small.
