I am a Crypto-Enthusiast but people need to realize that "being your own bank" is actually a paranoid nightmare of responsibility. Bitcoin, and other cryptos, are tremendously intimidating to the average person. Even I get nervous when sending any significant amount of crypto and I've been doing this for almost ten years now.

Just look at this: 17XiVVooLcdCUCMf9s4t4jTExacxwFS5uh

Now imagine telling the average person to take note of this and send the Bitcoin equivalent of $1,000 to it. Clearly, you would need to build a system around Bitcoin in order to make it user-friendly enough for the average person to ever feel comfortable using on a regular basis. At which point, though, you've just remade a bank and a payment processor.

What's the difference in scanning a QR code vs swiping a card? Even with CC you have to constantly enter it manually or store it in browser.

This is going to sound odd, but I think the QR code still carries the same level of 'unrecognizable' that a long string of alphanumeric text does. My brain can't really parse or recognize a QR code from memory. As such, I have a sense of unease. However, I am able to roughly recite my credit card number because it is 4 sets of 4 digit numbers.

But you're right that you can offload addresses to browser or app memory just like with credit cards and get rid of some of the trepidation that way.
