And yet, disputing charges via your bank and issuing chargebacks via VISA/Mastercard are things that definitely exist and work perfectly fine. And as long as there is no equivalent function in crypto, it won't be suitable as a currency for general use.

Cash transactions are done locally when you can typically inspect the object of the transaction before paying. That's why there is not the same need for these kinds of protection.
