> Bitcoin's slogan is 'be your own bank' which means you're ultimately responsible for your own security.

And this gets back to my original point. Security is hard enough that it's common for seasoned security professionals to not follow best practices. Regular members of the public don't have a chance if they have to assume all the responsibility of their own security - this is why they outsource that to banks right now. Hence: in order to manage your own security properly with bitcoin, you have to understand the underpinnings of it. How can a person be ultimately responsible for their own security if they aren't aware of even the most basic of security issues in tech?

Phone based AES hardware with fingerprint security, coupled with QR code scanning payments. Literally point and pay with biometric data.

Or should we use pieces of plastic/paper?

Well, biometric data has already been proven to be worth less than a password - because once it's compromised, that's it for life. You can't change your fingerprints.

But yes, pieces of plastic/paper don't require the user to have an expensive-yet-easily-lost doo-dad that is also hard to replace. Have your phone stolen? Now you have to wait not only until the banks do their bit, but also until the phone shops reopen so you can start buying things again. Not to mention that if you forget to charge your "money", you can no longer use your "money". It's also not an option for those in poverty, or for the plenty of people who don't have a phone, let alone a smartphone. "Dollars" come in a lot of forms that you can use at any point in life and in any state except perhaps severe mental illness. High-tech electronic-only money certainly does not.
