The discussion about the reduction as meaningless

Hello Rabbi,
After studying the book "No Man Has Dominion Over the Spirit" – as far as I understand, your claim is that the entire discussion surrounding the literal/indirect tzimsum is meaningless, because it is impossible to draw conclusions from it, these are empty words.
On the other hand, after that you present your own concept (the question of knowledge and choice, Torah in Gebra/Haftza, etc.) and there you constantly link your proofs to how they best demonstrate the concept of tzimtzum in its literal sense in practice.
Why do you keep making this link (you probably don't rely on it in your claims, but only as a link) if from your perspective the discussion is meaningless in the first place?
