USPS should have issued every American an official government email address 20 years ago
The USPS offers and redeems Postal Money Orders. There's your (inconvenient, expensive) payment processor right there.
Don’t you think they’ve got enough to do already with dwindling resources?

Sure, postal banking [0] has been around forever. Could it be updated to the modern day and in the US? Of course! Why not? Because we apparently just can't have nice things.
It's a perfectly good idea that just doesn't have political traction in this era.
We could also have, you know, universal health care. Like any other normal country.
