You don't have to actually be able to do it yourself for it to be beneficial. If I am, lets just say for the sake of argument, completely hopeless and don't know my quick web search pentalobes from my tri-points I should still be able to take a thing to a repair shop and they should be able to use standard tools to open it and use standard or at least affordable parts to repair it. We're not talking about "changing oil is hard" because you can take your car to a workshop and they'll do it for you. We're talking about you can't change the oil, you have to throw the car away and buy a new one.
