Not people, it’s more about adding an extra protection step for some services like a system management-only VPN or SSH (if not behind the VPN) and it shouldn’t be the only thing deployed. Fail2ban and others should be there as well.

After all it doesn’t make sense to allow access to your VPN from China or maybe restrict it to your country if you’re not traveling. There’s another use case that is, you need to access some service from another system where you can’t have a VPN and that system doesn’t have a static IP, this increases the security a bit. It should be narrowed down to the ISP ranges level but that’s not always possible.
