I think you are underestimating the value a person places on the time to put these pieces together. If you are a student, $20 is a big premium to pay to order a PI, an SD card and then downlaod some software to the SD card and install it.
I have a couple raspberry PIs I have used for various applications. I decided to put together an arcade emulator as a gift to my son. I know how to make this. But if someone sold a PI arcade emulator with the card installed I would pay $60-70. With a controller, a $100.
