It's a great point, but even that is becoming less and less true as the years go by. USPS is the only organization that guarantees physical delivery to every address in the US, yes.
But, nowadays information is increasingly distributed via SMS, email, twitter, whatever and the number of non-connected households steadily declines.
So, your point is well taken but the whole concept of the USPS will be, I think, rethought over the coming years.
