Traditional server-based self-hosting will have lower average uptime, will be easier to attack, and will have a much higher chance of disappearing out of nowhere (bus factor event, or for any other reason).
A decentralized or distributed solution would make more sense as a suggestion here. Radicale (this one) is such an effort I’m aware of, although I never tried it myself or take a look at its architecture.
