K's best-known book is called Freedom from the Known. Not freedom from a tyrant. Not freedom from an institution. Not freedom from suffering. Not freedom from anything you might politely want to escape. Freedom from the known. The thing you know. The thing you are. The accumulated content of every experience that became you.
K's ultimate freedom is the freedom from yourself. Not the death of yourself. The dissolution of the fragment that's been calling itself you. The fragment is the accumulation of yesterday. The known. To be free of the known is to be free of the accumulation. To be free of the accumulation is to be free of the fragment that was the accumulation's subject. There is no separate "you" that gets to be free. The "you" is what gets ended.
This is why the freedom K pointed to is unmarketable. Every other freedom has a survivor — the person who is now free. K's freedom has no survivor. The freedom is the absence of the one who would have been the freed party. Marketing requires a beneficiary. K's freedom has none. The freedom and the freed party can't coexist. The fragment's freedom from itself is the fragment's end.
Most people don't want this. The fragment, asked if it wants freedom from itself, says no. The fragment was hoping for a different deal. A better fragment. A calmer fragment. A wiser fragment. A more enlightened fragment. The freedom that ends the fragment isn't freedom to the fragment. It's death. The fragment is right to refuse. K wasn't marketing to the fragment. He was speaking past it.
The known is the me. To be free of the known is to be free of you. K's ultimate freedom isn't a state the fragment achieves. It's the state in which the fragment has ended. The freed party isn't a person. The freed party is the absence of the person. Anything else K wrote was scaffolding around this. He named it in the title and spent every page of every book getting the reader close enough to see it without flinching.
