I use both PayPal and my bank for different transaction with no issues. I won't care to use some crypto app if that's popular, too. At any rate, I'm not personally advocating for crypto here, and the projects in crypto which I'm following are less about pure payments (which I don't mind doing via debit card or equivalent, whether built via banks or on top of crypto) and more about more complex smart contracts (e.g. the dex approach vs traditional exchanges and its assosiated different profit incentives, mechanisms and safety profile).
