I'm at least an instance of one that demonstrates that it's possible. The person you link to sounds misconfigured to some degree, but in the main two things they don't mention are whether they are using static IPs (as I am), or if they tried emailing postmaster@ to try and smooth out their difficulties. There is still a collegial network of people who run this stuff all over the world, and I'm certainly not the only person running a closet mailserver.
Yes, maybe rhizome is successfully running his own personal mail server but your anecdote isn't really relevant. We can't learn from your example because the hidden rules of reputation & spam may not affect you but will affect others.
For example, a commenter (lucb1e) argued[0][1] that I was exaggerating the difficulties of reliably sending email but a year later in 2019, he confirmed the same difficulties! [2]
Do you see why we can't reliably extrapolate from personal experience?
