Maybe I don’t know what a monopoly is...I thought it was a situation in which there was only one entity able to provide the service. I’ll have to go back and check my vocabulary.
The mail boxes are part of the services provided by the post office, so you cannot put non-US mail in those boxes. But you could certainly walk up to the house with your Japanese mail and put it in an alternate box if you wished to do so. Newspapers around the country with rural routes do this all the time.
I have no idea what the neighborhood watch thingy has to do with monopolies...I’m stumped.
Aren't you just too cute by half, bless your heart?!
By your definition, AT&T was not a monopoly. And at least with AT&T, "their" infrastructure was not protected by the threat of a felony conviction.
