I kind of disagree on what you try to accomplish in your second half. If you want to live here, you should be exposed to local culture and language, and have a somewhat hard time retreating into your own, separate filter bubble. Sure, Youtube could find more effective ways to achieve that, maybe by more gradually introducing you to it (especially language). But with their current capabilities, I'd vote for them pushing location based crap over not doing anything.

Why should I be denied access to content I might be reasonably assumed to enjoy? What kind of weird argument is that? From my point of view it's just a good example of broken assumptions in what is obviously a not very sophisticated way to promote and recommend content.
I am not sure where you've seen anyone advocate you to "denied access to content". We are talking about a recommendation system. Those are pushing content, and as such include believes, values, etc. This makes companies have a responsibility on what they advocate for and what effect that will have on our societies. If you're talking about opportunity cost: Well, an imaginary flat earth'er or science denier would say the same about getting recommended stuff beyond his bubble.
