I would prefer it if restaurants started accepting cryptocurrencies. I don't really enjoy the fact that paying with a credit card lets both visa and my bank to know where I eat.
Not to mention that credit cards are a giant pain in general, "this transaction was declined".

That's a completely different problem with completely different implications. Doesn't matter if you pay with cash or credit card, dollars are still dollars and are regulated by the Federal Reserve.
To change to cryoptocurrencies is to leave the dollar. So it is not about how you transfer money, but about which currency you work with.
