Most people shouldn’t self host. It’s a hobby for people who want to do it, and there are benefits, but spending 3 hours on a weekend fixing stuff is not how most people wish to spend their time. Furthermore, it’s not a good use of most people’s time. We split labor up into specialties, forcing people to do work outside their specialty causes pointless inefficiency. I agree with what other commenters have said in that a better approach would be to have more small businesses hosting federated together, and anyone not inclined to self host should just purchase service through one of those many small providers instead.
