Hosting for yourself so you can access your content outside your home is usually the use-case, use WireGuard for that though (checkout headscale) along with virtualization, VLANs, etc.
Hosting for a group of friends and/or family can usually be ok, assuming that is a well known and restrict group.

Hosting for the general public from home is usually not recommended, use a VPS for that. Bear in mind you’ll likely be liable for what you host, one way or the other, depending on your jurisdiction.
If you store content (files others may upload like movies and photos) you may be responsible for that (i.e. is that content legal in your jurisdiction?).
There may be a legal distinction between the server’s geographic location and the entity responsible for it - but in your case it’s the same, so, again, beware.
Just linking to content deemed illegal may get you into trouble.
Putting the site behind a login-only page and vetting account creation could mitigate (or exponentiate) this.
Anyway IANAL.

What do you want to host and for whom?

Maybe headscale will do better?

Dunno (yet); i’d assume they’d scan your wallet QR?

I haven’t explored that yet as here is none nearby. There aren’t many vendors of these machines.

You may have an ATM near you.

You’ll be frowned upon. Severely.

You obviously didn’t format it.

virt-manager supports, at least, kvm and lxc/incus, so you should be fine.

The access is limited but of course…

I’m happy with FeedBro (browser extension), very customizable.

Microwave. Strong magnets. Drills. Scrapyard shredders. Volcanoes.

Does Dokuwiki count?

You’re probably thinking of PairDrop (which also allows extranet).

You can OnionShare if you’re worried about privacy.

Oh no…
Anyway…

Yes.

I know owning my domain will give me freedom to move my email elsewhere if I would want but I dont know if its worth it.

If you can’t answer neither can i.

whois lookup privacy?

Many tiers to chose from and no one will check if you live in Nowhere St 1337 anyway.

Proton and Tuta also offer custom domains.

IVPN perhaps?

Not being an expert it seems as though your setup is windows-centric, whereas KVM tends to shine on linux.
