UPD and Fed Ex also arent' delivering to every home in America every day either, which the USPS was mandated to do...by that very paper you need your AK47 to defend...the US Constitution. Don't tell me...the constitution needs to be changed to address that, but not your AR15...right?
USPS model for success doesn't seem to be working very well.
Didn't UPS and Fedex want to go into the mail business a few years back?
But weren't allowed?
