The only way the sovereign nation of France can ban VPN companies not based in France is to block the IP address of every single entry point of every single VPN company and keep doing so as they add new entry points (I bet the response on the VPN company side would be to start having some kind of dynamic VPN server thing).
And then, as somebody else already pointed out, any technically inclined person can just rent a VPS anywhere in the World and fire up their own VPN server on it.
The VPNs will be harder to ban. Not just from a technical standpoint, but politically as well. Big businesses will be absolutely opposed to VPN bans.
There will be a lot of businesses who feel the (justified) need to hide the entrypoint to their infrastructure behind a VPN.
I feel they could easily ban VPN companies (maybe?), which is what 99.9% of people that want to browse from a different location use.
This won’t affect companies at all as they would be using their own VPN.
VPN becomes VPS and life goes on.
