I would add as an indirect reply to the poster you’re replying to, that most people know about VPNs because of exactly the point you make. Loads of VPN businesses are out there and they’re advertising in the mainstream about how they protect you from hackers, your ISP, ambiguous WiFi shenanigans, etc. Those businesses have made VPNs fairly common and point-and-click easy to use. Even where they use the same protocols (IPsec, OpenVPN, WireGuard, et al) that you’d use as a technical person, they’ve wrapped them in mom-and-pop GUIs to make them accessible to the masses.
