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.
