In future publishers will probably use web assembly for DRM, for example, to render decrypted article text on a canvas so that it cannot be copied, zoomed, read aloud or viewed without advertisement and annoying popups. Maybe you will change your mind about Javascript then.

It wouldn't run without JavaScript being enabled, for one.
