Very few people know this but.

Information entropy and statistical mechanical entropy are two different things.

They share the same equation and the same name but they are two unrelated concepts. You have conflated the two. The person you are responding to is referring to statistical entropy.

Basically in this entire thread nobody, including you, is fully grasping the situation.

They are not at all unrelated. It is not easy to grasp, so I understand the confusion. https://en.m.wikipedia.org/wiki/Landauer%27s_principle

Fun rabbit hole would start with classic paper by jaynes

Many more recent examples relating bit erasure costs of computation. Some names to look up if interested include charlie Bennet,Dave wolpert, James crutchfield, Susanne still, for starters.

Edit -- a collection of ideas related to this problem and mixing in "complexity" can be found in SFI proceedings called "Complexity, entropy, and the physics of information"

I respectfully disagree. Perhaps you'd like to present more than a mere assertion to make your case. I did.

If it helps, here's a paper that explains my stance in more detail. https://bayes.wustl.edu/etj/articles/theory.1.pdf

If you think there is no relation between the different things called entropy apart from the name maybe you're not fully grasping the situation either.
