I can't even begin to parse what this post is supposed to mean.
The yummiest slice of the cake is the part I didn't eat.*
.... there was a certain quality that I enjoyed with your title. Now, I think what you were getting at was, "Pre-written Adventures (modules, APs) are much better if you carefully edit them ahead of time and remove material that doesn't work."
But instead we end up with this amazing zen koan.
Reynard, a DM during the Meiji era, received some youngling DMs who came to inquire about Zen D&D.
Reynard showed the younglings copies of Dragon Heist, explaing that he would be showing them how to run it.
Reynard then began shredding the pages of the adventure. Page after page did Reynard shred, completely destroying those pages.
The younglings watched the watched the destruction of the adventures until they could no longer restrain himself. “You have destroyed more than 2/3 of the module. What are we to run now?”
“Ah,” Reynard said, “what is left is not the adventure, but merely what is "not to run." That which has been destroyed is what you must learn.”
