But then this is exactly down the road to authoritarianism. I understand and support that companies have to comply to the laws of the country where they are operating/targeting an audience. If worldwide dispersion of content banned in your country is such a concern, you can either push it to the UN OR you make according deals with the states harboring the companies. Otherwise you can go down the great firewall route and there's little difference between that and forcing hoster to effectively implement the firewall worldwide. Real-life example: weed is legal in the Netherlands. So all neighbors could now force the Dutch to close all coffeeshops OR block all their citizens from entering the Netherlands. I don't see any difference to this case.
