Most of the time for bureaucratic legalese you would need a local specialist either way, even if the documents were written in English because you need to know local laws (or where to look them up) also. Going back to the Netherlands example, I think that's a totally reasonable behavior on their part, yet never has been an issue to me not knowing Dutch, nor has been an issue to me not knowing Danish in Denmark. But for regular daily activities - Uber, restaurant, healthcare - communication is fluent and that's what matters for those living there temporary.
