The last part is interesting, you could make a point that some form of entertainment or junk food are a light form of drugs. And those are illegal.
Almost any substance can be abused though. Where would you draw the line? Should we ban (or put more tax) on candies? Soft drinks? Salt? Carbohydrates?*
Personally I probably draw the line quite far from you, I think many drugs could be legal and it wouldn't shatter society, maybe it could even improve it. But that's disagreement about the line.
My general point is that even if we would agree that people should watch more EU content, then forcing it on them is like when you have some complex algorithm (like in these coding contests), and some test cases fail. And instead of trying to rethink the algorithm, you add a few IFs, to make those test cases green. You can find examples of workarounds that would have the opposite effect (like netflix providing less content so that % matches) that people came up in minutes after reading about it. And in case of legislation it's much harder to get rid of those unnecessary IFs later on, than it is to add them. Anybody who's trying to innovate then has to navigate around them. Law is already so complex that everyday citizen can just hope he doesn't break any. He cannot be sure, because it gets created faster than you can read and understand it, even if you would make that your only hobby.
