No, that doesn't work. If anybody could say what should happen globally, and nobody would argue about it, then we wouldn't need courts and borders. The whole point of courts and borders and jurisdictions is to resolve disputes. We wouldn't have copyright law if there weren't copyright disputes. So you can't just say "if any court anywhere decides something, it should apply globally." Because the next court over, in the next jurisdiction, can rule the opposite way. What then?
