If you are above the retirement age, you should not run for an elected office. If you exceed the mean life expectancy, you should be prohibited from serving.
If you expect a voice in shaping the future of the country, you need to have an expected future.
You still need a public IP address. More and more often, IPv4 services are provided behind CGNAT, which won’t be able to work as you describe.
If you don’t have a public IPv4 for your LAN you can use IPv6. Or, you can reverse proxy your services through a gateway with a public IPv4.
I use a a reverse proxy (Pangolin) running on a VPS. A Newt tunnel connects my LAN to to Pangolin, exposing my local services via subdomains.
Tailscale, ZeroTier, and other similar services generally establish direct tunnels between devices, without a separate VPN server. They use a central service merely as a sort of common meeting point (STUN/TURN) for the devices to figure out how to establish direct tunnel(s).
