I grew up through the 80s and 90s too and I'm not sure why you're that concerned: - we mainly all still have global IP access on our broadband - HTTP and SMTP are still fundamentally text even if you need TLS (just need the key to be able to read it) - HTTP/2 has clear semantics that can make it look like text with a simple script - NAT is annoying and yet essential ; it will be in an IPv6 world too. the dream of everything having a public IPv6 address was always unlikely precisely because people want privacy for their devices, a (misplaced?) belief they're one step off the grid. I suspect the work we are seeing with cloud technology around automated dynamic provisioning of firewall & routing will make its way into consumer edge routers and ISPs some day when the right app is there. Tinkerers always find a way.
