It's absurd how difficult it's to repair a MacBook. I have a 2009 MacBook that needed to have its keyboard replaced after my mother dropped coffee on it. Not only I had to disassemble the ENTIRE MacBook to reach the keyboard, the keyboard itself is covered by a plastic sheet that is super glued to both the MacBook and the keyboard. It took an enormous amount of time to remove the glue, and not only the keyboard was completely destroyed in the process, the case itself cracked a little bit due to the amount of force needed to remove said plastic sheet. And that's without even mentioning that there was at least 3 different types of security screws before even reaching this point.
Yes and look at Macbook 12 retina [1] and remember.. keyboard is one of the things to worn out quickly and can also be easily damaged by liquid spill. Also notice the video is fast-forwarded many times during the procedure.
