Are principles not important for self-defense Sir?
If it teaches principles and those principles are not important for self-defense, why bother teaching it?
What principles does it teach? Will what it teaches differ based on the student's learning ability and the instructor's ability to explain and train the knowledge it contains or does the execution of the set as is without isolation, application or further explanation ingrain correct principles that transfer over during combat?
Are any of the Forms, sets and longer techniques really worth more then dancing to a good song without being explained in detail, taken apart and worked on bit by bit until the end result is more then by the book execution...
In fact that is a good way to think of it, a lot of the system is like a science book and reading it is not enough, you got to work on the application of the knowledge in each chapter until you can read between the lines and see all that is not there.
