This was a great read and goes to show how broken email has become… I often wonder if we will ever migrate to something better collectively, or we end up on a variety of different communication platforms.
My point (albeit subtly made) was that there isn't a central authority that controls emails, you can't just buy emails and then run it as a national service. And that's before you look into which government runs what.
All of them ofc. Instead of a few companies controlling an essential service, what's stopping a government from offering every citizen an address at yourid@govmail.country?
