The main point of the article is not that Arabic has a list of things that are impossible to find in any other language. It is that Arabic has many intriguing features that are in contrast to what a native English speaker might be used to. (This is about native English speakers learning Arabic, not Arabic vs. The World.) When English speakers look to learn an "exotic language", the general go-tos are Chinese and Japanese, which have comparatively very simple grammars. Thus in the exotic language category, as the author points out, Arabic is a very intriguing choice. (And while many Indo-European languages may share a few related grammar rules, using the Latin alphabet hurts your candidacy as an exotic language.)
