The multilingual in our family includes one large language, one Asian "national" language, and one Indigenous language with < 500,000 speakers and fewer every year.
I agree with you that, for each place there are language politics that create oppression. In Scotland, it would make sense to encourage polyglossia in Syrian Arabic, in Farsi, in Kurdish, in Albanian...as well as Scots and Gaelic...as well as Polish, Lithuanian, Latvian, Swedish, Bangla, Urdu...and in fact I work on projects that do this. But just getting the monoglots to see that monoglossia is both oppressive and also an unfreedom is hard when it is a marker of privilege.
And I wory desperately about #endangeredIndigenousLanguages like the one we speak at home. So much is lost when a language dies.
