I think some of those barriers are going away ( in the UK it's now possible to get symmetric full fibre at a reasonable price ), static IPs, ISP's without filtering etc.

I think the main barrier is still the complexity of running your own service - it's a full time job to keep on top of the bad actors.

For example, if you have your own domain it's perfectly possible to run your own email server - however it's quite a lot of ongoing effort - it's not just set up and forget.

I have seen those kinds of opinions on internet already few times. No it is not that complicated. Yes you need to buy server. Yes you need to setup the DNS. Yes you need to maintain, and update server and its software. But this is like that with everything you selfhost.

Beside that you need mostly 1 time operations like: - setup domain entries - setup SPF - setup DKIM - setup certs - install server (of course) - test if this works - setup some Google Postmaster account because they do not like new domains sending them emails

I do not remember anything else beside some administrative tweaks here and there. But!

I never attempted to run postfix, dovecot combo myself. I was aiming to run whole thing on Docker and forget about configuring dozens of config files on Linux host. With docker you can just migrate whole set of volumes to new machine and that is it. I am running Mailcow BTW.

Lately I moved whole thing to new machine by just running one script https://docs.mailcow.email/backup_restore/b_n_r-coldstandby/...

On the other hand you need to have some technical knowledge, but I do not think this is harder then any other containerized software.
