As I responded in a sibling comment, that is true when you are being targeted: for blanket surveillance of innocent citizens, it will work wonders.
The problem with just doing encryption is that it can be made illegal and it's obvious when you are using it with a cloud platform. The same is true for steganography (you can make it illegal), but someone would have to know you are using it to apply the same tactic.
Oh absolutely, I once saw research exploring how terrorist groups were using World of Warcraft emotes as their steganography and I show my students how to do simple least significant bit hiding when I teach them about image processing.
Unless you know for a fact someone is using hidden communication its near impossible to discern in the wild.
