Licensed banks aren't getting pillaged by cyber criminals though, I'm tech literate and mindful of my security and yet my 3 bitcoins were stolen from Mt Gox. People buy hardware ledgers to create a higher sense of security then those get hacked. The money in my bank so far has never been touched without me having to think about it at all.

Presumably you would keep most of your money in a licensed bank and only a small fraction as cash: either in a digital wallet on your phone or a leather wallet in your pocket.

Being able to complete small purchases P2P offline without needing the whole MC/Visa/Square/Stripe stack would be fantastic.
