> If we want to improve on this, it has to come with the current level of ease of use at a minimum.

We need to recognise that is impossible. Making getting into a bank account easier for the owner does so for everyone else too. And also makes it easier for the bank to ditch the secure fallback - a building.

And ask why vendor-indepedent trust shops aren't sprouting in every locale. Answer: same security problems.

We are well and truly doomed to living in a scammers' paradise.

But my bank has no physical buildings whatsoever?

And also, how is my bank supposed to safely generate and distribute a key that we can exchange securely if an organisations who's primary purpose to generate these keys couldn't even manage to do so.

I have plenty of other services I use too. Suddenly my phone company, doctors, supermarket has to create and distribute keys for me to go around collecting so that I can securely talk to them and we have to do this in a way that stops anyone from swapping those keys out before they get to me.

I mean the current system isn't perfect, but it's a Utopia compared to that.
