I'm more concerned that it may be drastically expensive-- or completely unavailable-- for rural people to receive packages. Right now UPS/FedEx/etc don't go everywhere and rely upon USPS for last mile in many areas.
You know what? The best solution is lifting taxes (most of them don't pay much anyway) and usual phone bills (that are freaking expensive for the service it provides). it will probably cost less than to pay for the last mile.
