So i have a few questions..
If ANON was needed so badly why did the dev's not submit the idea to the Bitcoin core dev's foundation etc ?
Was it because they knew it would be rejected ?
Well, you'd have to redo many things in bitcoin. So many, actually, that almost nothing would be left of bitcoin. Your question is akin to "if flying in the air is so important, why did people build airplanes, and didn't add wings to cars which were already riding ?". There's so much to change in a car to turn it into an airplane, that it is easier to start off from scratch.
Now that's a nice comparison, I'm jealous of the way you can explain things in layman's terms like this... Even someone who never heard of crypto can get what you want to say with the above explanation...
