I think you mean "You should never use Django unless you're building a social network". A lot of your arguments seem to only apply to the old guard of frameworks Django, Angular 1, etc...Where there would always be "The X way of doing it..." All of the popular modern JavaScript frameworks are easy to learn, increase flexibility and creativity, are themselves mostly high powered versions of the core language (no useless knowledge after learning), generally small, and in no way are Facebook, Google, or Microsoft about to abandon React, TypeScript, Angular et al... And that's just front end frameworks. Express and Koa do nothing to mystify idiomatic JavaScript or server development, and are just implementations of popular, easy to understand programming patterns.
