Sure, but how long would your new server keep working (i.e., delivering mail to GMail, etc)? Do you know some magic incantation for staying off the naughty lists?
Setting up a server is trivial, yes. Keeping it going is a never-ending treadmill of not really technical problems.

Not magic, but when I managed outgoing Postfix servers for a few companies I had to set rate limits for yahoo.com an a couple other domains to reduce concurrency or they would block one of the SNAT's for a while. It probably sounds tedious but it really wasn't. There were not many MX that were as strict as Yahoo. I never ran into issues with Gmail but I think they cut some slack for corporate IP addresses and domain names.
For my own personal email servers I never had issues because I never sent at a rate that anyone cared about. The closest I got to that was running a forum that would email when threads would get updated and people subscribed to them but my solution there was to suggest to the people on the forum not to do that.

I can't see the future, if the big email providers who likely have some of their trolls posting in the comments ever decide to start choking out us personal email server runners, then it'd be game over. If things remain for the next 20 years assuming I live that long then deliverability would be 100% for the next 20 years.

I don't spam, that and don't make a finger fumble edit like I did the one time in over 20 years and didn't check to make sure it was working correctly first.
