No, having quality spam and fraud filtering, and quality security, that you host yourself, is by far the much harder problem. I would argue that outsourcing your email to Proton or Tutanota is not running your own "artisanal" email server. By the way, even with those email providers, I still have terrible spam and fraud emails getting through filters that I never would have seen with my GMail.
I just don't see what people see in gmail part from the google brand - which surely isn't a good thing anymore.
Most people I know? It is almost a daily occurrence. Including if senders are in address books, and "not spam" is clicked when found in the spam folder.
Most people I know see legit emails in the spam folder, all the time.
So far I've been lucky to rarely receive actual spam, but I've often missed out on important emails too often.
My experience is similar, I receive much less spam on my actual mail than I do on gmail.
That's not a claim I'm making. The goal of my message was merely to help people see that there are several steps you can take from using a gmail account to relying on no third party. When I talk to people, they often don't realize this, and especially, how easy it is to set up #1.

Handling spam is not an easy problem, but it's one where you have all the cards to take actions. On the other hand, having your mail properly delivered is something where people have wildly different outcomes, and for people with bad outcomes it's "impossibly hard, and there's no action you can take about it, unless you personally know the right people at the right places".
