You're missing the point.
I said there is no US law that states that home delivery is a right or entitlement.
If you were to send me a package from your address to mine, it would not come to my home.
I do not have home delivery. I have to go to the post office and pick up my mail.
I don't have a PO Box address, I have a street address, and UPS and FedEx will deliver there. The post office does not. So, if you were to send me package, I would tell you that I have to go to the Post Office to pick it up. It's not an uncommon thing in rural areas.
