How ironic that you do not even realise how entitled you are to make such a remark. The EU is regulating its own markets. The US is trying to stop the EU from trading with Iran.
You said it: non-arbitrary
Think about what you're saying. If you read British history, the empire before this one, we used military dominance to force China to allow our companies to deal opium to their society, totally ravaging it. You're makinga similar argument except instead of opium it's surveillance capitalism. Whether or not you think SC is bad, it's hard to justify why countries shouldn't be allowed to take their own approach to what's allowed through their borders. And why countries should allow companies with natural monopolies and mayb massive profit margins to basically milk their citizens. Honestly I wish the EU /really/ did tech protectionism.
