Self-hosting is trivial and everyone can do it.
Exposing services to the internet is not.
Just like everyone doing open heart surgery on dummies is fine, everyone self-hosting in their own network is fine. You can buy hardware right now that connects to power and wifi and you are self-hosting.

I finally moved my mail server from Hetzner to my homelab.
Pretty smooth sailing so far. For now I’m using Scaleway for outgoing mails since I can’t set a PTR record here but I might just try sending a few without PTR to see how other providers react.
