Interesting idea - but it boils down to being a workaround for the lack of persistently connected and pervasively VPN-ed personal devices around us.

Yes, we could have a VPS per person being our fixed point on the Internet (and a fixed address...) but wouldn't it be better to return to the original idea of the Internet with devices always connected and routable? It might take an overlay network such as a DHT-like thing, it might be something IPFS or Torrents eventually lead to, but the end game is "everyone always on-line."
