Indeed, however. i don't see how this solution is relevant to your OP. If I'm hosting my own VPN and then post on Nostr then what ever client i used has that IP. Your OP seems more like a YouTube AD for VPN's. (hackers are sniffing your internet traffic on public WiFi, get a VPN. so a middleman you pay, can sniff your traffic) self hosting your own VPN is an entirely different use case and threat model. 

 Hmm. Not everyone is out to get you. Maybe you aren't familiar with Mullvad VPN if you've hosted your own VPN for over a decade such as myself. They were raided and asked to hand over user data by authorities and were unable to comply because they have no user data 🤣
