That is where all this talk about "what will the Post Office do in the age of ..." goes - they will help me manage all this stuff and rubbish. I will trust the post office to open and scan my mail, far more than I will JRandomStartup.
And then they can handle a one stop bill payment service for me, and as I trust them, they can generate a CA and I will put it in my phone and suddenly they own the customer experience for everyone.
