You are missing out the whole idea of a PhD. It's not like any other degree where you opt for some courses, you sit in some exams, you are graded and then you have a certificate. A "PhD" is a process; a journey where you learn by experience and failures. You learn to design your experiments; frame your own questions; develop a sense of problem solving. You fail at times and learn by mistakes and move on. That entire process ; that journey, polish you as a scientist. You develop abilities that you apply in other areas when you done with it. You miss all of this is a part time or distance PhD.
