Why is the new Unity UI so insane?

Hello, March 2015. My aren't you a crazy cold one aren't you? (About a foot of snow covers everything as far as I can see out my window...)

Well my first encounter with Unity's new UI has left me searching for answers to something that really shouldn't have been a question. What? The retarded over-sized Canvas that gets drawn in the Scene view. What the hell were the Unity devs thinking?

This sums up the problem with Unity UI Canvas pretty well.

The image above I found in a thread on the Unity forums. Credit to the owner. It is not mine. And I think that it sums up the problem with Unity UI rather perfectly. I'm using the Unity 2D Sprite system to create my game, and then I was going to add the menu using the shiny new UI system, and a hair-pulling, mind-numbing truly baffling situation occurs when one tries to add in a menu. I added in a Button control to my scene, which tosses in the Canvas and EventSystem objects as well. But the Text on the Button never showed up. Why? Because the stupid text was sitting about 4000 pixels off screen!

After a few google searches, I learned that this is the proper behavior of Unity UI. Why? I don't know why. It's stupid. But once you know about this really stupid design, then you can get down to using the seriously powerful and useful Unity UI.
