You choose to have Google spying devices at home. You choose to have Gmail. You may have no choice for Internet search for quite some time, but you certainly choose your browser.

Disagree with this. self hosting email is notoriously difficult. Gotta give the data to somebody. Plus, your work email is either going through MSFT or GOOG, 99% of the time
You can't even ask tech people to make a choice for you because they all say different things.
Other domains like cars, medicine, construction, whatever have established standards because they have recognized that individuals simply _cannot_ make an informed choice, even if they want. I'm eager to say that only information technology likes to call the user "unwilling" and "lazy" instead, but actually individuals from other domains do that too. Luckily, the established standards are mandatory, so their opinion doesn't count.
Yet people do it anyway. It's not an impossible task like you're making out.
You can have DMARC, SPF and DKIM all correctly configured on a clean IP and some mail server at Microsoft will still drop your mails because it's having a hard day and it feels like it.
That place in particular (which I use and can recommend) even have a (permanent?) free tier. ;)
If you're serious about this than go talk to a non-tech person and tell them to self-host email and see how they do. Look at their challenges, build a solution and then offer it.
That's not at all what the conversation is about, and routing through an external place removes a whole bunch of hassle compared to setting up and maintaining outbound email.
You might not like it for some reason, but that's on you.
What's the point? At that stage you've already conceded the deliverability problem so now you're just wasting time administrating dovecot and keeping up with security patches.
Obviously yes. Not sure why you're trying to pretend otherwise.
Good luck with that. ;)
