I'd say that even the idea that you could VPN into your own network and forward all traffic through it is pretty far from the mainstream. Let alone how to actually do it. Most people think of VPN as a way to avoid porn blocks or getting tagged for piracy. But, as you and I both noted, the technical know-how for setting up Tailscale is not that high, and for using it is almost nil. Turn it on, pick an exit node, go. Combine that with a device that's intended as a consumer appliance that makes maintenance a non-issue, and you have a very good solution for the family geek.

You're very welcome.
