I responded no. You come back with some out of scope non-sense about thinking outside of me. That's not the question.
If the question was "should the mail system be abolished", we can have the discussion you want, but maybe you should ask that question. The original question as actually posted followed with "yes we still need them".
Most people have phones. For those who don't, alternate infrastructure that leverages the internet could easily exist, and would be way more efficient than the USPS network.
Watch this get downvoted, because people really emotionally _care_ about USPS.
That said the USPS is certainly an essential service and probably does serve certain niche locations better than UPS & Fedex.
FedEx won't tell me the cost without an account, but for UPS a domestic, ground letter (<1 lb) costs between $8.76 and $11.01, or $32+ for Alaska/Hawaii etc. Added to that, "remote areas" have a surcharge which is about $4 in the 48 states, $10 in Hawaii and $32 in Alaska.

I always hated USPS when I lived in the US. Service at the post office was usually terrible, clerks were clearly coasting on the fact that they were hard to fire (customer service was poor), and delivery rates were hit and miss (whereas somehow the private carriers always managed to delivery.)
Now I live in a country with no mail service. It's fine. I do everything online. If I need to order something, I pick it up from the DHL store in town. The one time that something was sent via certified delivery, a motorcycle messenger delivered it.
Public services that our government provides are done so without regards to people’s ability to use email, electronic banking, or drive to the nearest FedEx/UPS store in the closest city.
