At what cost? What benefit is sending non refusable spam to the ends of the US to anyone besides spammers? You don’t accept spam email do you? Would you support it if it physically existed and your taxes paid for it, including costly methods like sending it to the middle of nowhere?
Well we kinda want some people to live in the middle of nowhere, because we want to eat and somewhere isn't where farmland is, apparently.
Also we kinda want to keep territories like Alaska inhabited because geopolitics.
And we kinda want the people living in those places to be able to get their official government documents (driver licenses, court notices, etc).
Then there's this idea of voting by mail, which isn't something that should be a privilege, but that's too complex for our discussion.
To translate one of the reasons for USPS into words you may understand: you know how two-factor authentication requires that second factor? The USPS provides a means for the gov to get that second factor into the hands of the people.
A third party would be a man-in-the-middle.
So consiser USPS a part of the government's 2FA infrastructure and messaging system with SLA and proof of delivery.
That, unlike your company's authentication infrastructure, happens to pay for itself.
Not having the USPS won’t affect that. I know someone who lives in Alaska and if you think the USPS delivers there or in a timely manner, you’re mistaken, it’s seasonal and not USPS. The oil payments and other incentives do fine, nobody is there because USPS can spam you. If we could have spam block, I wouldn’t be against it as much, we shouldn’t cut down trees so you can have ads forced into your home without consent.
If you think farmers are quaint small independent workers, you’re also mistaken, they’re extremely educated, very high tech, and have Internet, the idea of them being hicks that use mail is outdated by decades.
Mail in voting should be skipped over for online voting. We have all the information online and could reach more voters, cities have many more options and rural areas are more easily reached by internet than physical mail. Developing counties skipped home phones for cellular, this is a complex unnecessary step.
