No, we don't need latin, or greek roots, to enjoy our language, and there's just as much if not more of a reason to use roots natural to our language, and no you aren't smarter or wiser, more scholarly or intellectual, because you use big long fancy sounding latin or greek based words.
maybe the reason a lot of english doesn't make sense (in contrast to german) is because we replaced a lot of words we might join to create new meanings with greek words"But there is also the further idea that Anglish is a recognition and a celebration of the English part of modern English. For, although it has borrowed thousands and thousands of words throughout its life, there still exists a true English core to English, the most important everyday words which no sentence or uttering could manage without. By stripping away the layers of borrowings, Anglish lets us better appreciate that core and the role it plays in our language."
