The last part about it breaking can of course be true, although knock on wood has not happened to me in quite some time. But I don't find myself spending all that much time on my selfhosting setup day to day. Once a week I do a backup to external storage and upgrade software and that's it most of the time. Once everything's set up it is mostly quite hands off.

That said, I also don't think selfhosting is a realistic solution for most people.
