The imperative of "Turing Completeness" often serves as a 'persuasive marketing ploy'. Achieving robust functionality & security in the realm of blockchain Tech doesn't inherently hinge on Turing completeness. No!

It’s all about structured scripting languages coupled with consensus mechanisms & principles of cryptographic algorithms.

I think, focus should be remain on 'cryptographic integrity, consensus efficiency & smart design choices' not an arbitrary pursuit of Turing completeness!
