This is basically what I do with my hobby sites. I have HAProxy sprinkled around the internet here and there. I set the custom header with the client IP address to something that my web server doesn't recognize. This means everyone on the internet shows up as my VPN address. This also forces me to ignore IP addresses and design protection ACL's to be generalized. It has been a fun learning exercise. That said, I am not suggesting that businesses should or could do this. Some businesses are required through regulations to capture IP addresses of their customers at a minimum.
