There was a startup called Outbox awhile back that was trying to be a proxy service for physical mail- have your mail forwarded to them (or maybe they picked it up manually?) and they digitized it for you. This idea from USPS isn't quite that but a good step in the right direction. Super handy for more transient urban millennials at least.

They did pick it up in person. You sent them a picture of your key and they made a copy, then picked up your mail for processing. I loved the service. But it was a huge logistical problem, and the USPS was antagonistic towards them. Ultimately they gave up on trying to move that needle and became Able (https://www.ablelending.com/)

There's one running now called Virtual Post Mail.

Earth Class Mail does it too.
