How do I enforce that? - They probably got no office in my country. No representative I can arrest.

Maybe I can confiscate money paid for ad's or something, however that probably runs via a payment system outside my control.

So I have to punish my local companies advertising, but then it won't be my local branch of Coca-Cola advertising, but a foreign branch.

Enforcing this, without international cooperation, is tough. And currently international politics aren't in a cooperative phase for large parts.
