If you're doing this for security you are better off renting a VPS or server and hosting it yourself. I would have trouble trusting a VPN service as there's no way of knowing if it's some kind of honey pot by the government or megacorps that will simply sell all your info.
Though even if you do host your own and you're the only user then it kinda defeats the purpose too... The only decent thing now days is mesh networking. Darknets, Tor, that kind of stuff. Idealy, a combination of things.
I've been wanting to look into Hyperboria and maybe even starting a node myself, just have not really had the time to play with it. It's basically a whole new internet on top of existing internet, but with plans to eventually physically branch off.
