In the days of the internet "operate in a country" == "exist". Eg: [1] UK has tried to enforce its laws even onto organizations who literally exist in USA only. Their argument: you exist, internet exists, so you are still subject to us. So tell me, how can one exist today and not "operate" in every country where internet exists. And once you see that there is no way, how do you propose your logic for regulation to work, other than by everyone being subject to everyone's rules?
