My brother in Christ you have described almost the exact same specs I visualized. The only difference is in the level of resolution of my "scene." And by that, I mean essentially I did a few more render passes in my head to anchor everything you've written within a sort of Impressionistic, highly softened, out-of-focus backdrop. I saw hints of shadowy cabinets, the concept of a darkened kitchen out of sight. The shape and finger placement of my slightly more textured, clothed yet featureless male. The gray-brown feeling of a floor below, a dark white ceiling above, and the faded glow of sunlight through an unseen dining room window grazing one end of that oaken table.
But the basics ... They're the same, and before being asked to recall them. Damn.
What if we work backwards on this?
Introduce community boxes at junction points where USPS already delivers, and/or next to a parks so you can say hi to your neighbors and stuff. Ensure any box is within a tolerable walking distance for the average community member served. (Best figure five minutes here folks.)
Allow residents with mail being delivered to their physical addresses to opt in to delivery at their associated neighborhood box.
Market the boxes as happy medium between visiting a staffed post office at the center of a city and risky doorstep delivery. Locked boxes large enough to accommodate everyday parcels basically nix those pesky pilfering porch pirates.
Continue regularly scheduled deliveries to individual addresses because the route will continue to exist at some level of specificity anyway no matter how many or how few community boxes materialize. Carriers essentially keep the same routes but get to drop mad loads of ~~male~~ mail into a bunch of ready and willing local slots near you, driving efficiency up and logistics strategists wild.
Promote additional box patronage by offering a slight discount whenever postage/shipping is purchased for a specific physical address utilizing delivery to a community box. Immediate and total coverage of community boxes across America is neither expected nor necessary, but hell, reward those who lighten that load for others.
Thank you for coming to my TED talk!
