I do kinda see why Crockford does all of that. Crockford, before the JSON fame, worked on a distributed language E and believes that "the next paradigm will be globally distributed, secure, eventual programming" [1], so all existing languages are old and JS happened to be the best transitional language among them. Assuming this is a sincere belief, Crockford should've tried to steer JS to suit this vision, and if that's not possible, to throw JS away and recommend other languages or make a new one. And I have a strong suspicion that Crockford is not as sincere as Crockford wants to be seen.
