It can't work mathematically unless it is from any EU country. There are more than 3 EU countries, which means that eventually you will get some great content from some other country that you are not allowed to access. That is 30% Irish, 30% French, 30% German, and 30% Italian content already doesn't add up, meaning some things that you personally might want from a different country are on the list of things you are not allowed to access even though the streaming provider you are on has all rights.
If it can be from any EU country, then the country will be France. France already has laws like this and has historically invested in their content industry, so it should be (should) fairly easy to license that content and fills the requirements.
Once you have an amazon.com account, you magically also have an amazon.de account, and an amazon.it account... and it's a few clicks to switch in the app. Maybe that's how it'll go?
maybe. However in most countries the courts tend to see through such things. I wouldn't be surprised if Amazon doesn't risk this loophole. If they do (even accidentally) I expect some lawyer will sue - there are a bunch of EU countries to choose which to sue in, the results might be different in each.
