If you lie to people, they should trust you less. Observing you lying should reduce their confidence in your statements. However, there is nothing in the fundamental rules of the universe that say that people notice when they are deceived, even after the fact, or that they will trust you less by any amount. Believing that lying, or even being caught lying, will result in total collapse of confidence without further justification is falling for the just-world fallacy.
If you saw a man lying to his child about the death of the family dog, you wouldn’t (hopefully) immediately refuse to ever have business dealings with such a deceptive, amoral individual. Believing that all lies are equivalent, or that lie frequency does not matter, is to fall for the fallacy of grey.
“Unethical” and “deceptive” are different. See hpmor ch51 for hpmor!Harry agreeing to lie for moral reasons. See also counterarguments to Kant’s Categorical Imperative (lying is always wrong, literally never lie).
The point about information theory stands.
Note that “importance” can be broadly construed as “relevance to the practical question of lying to actual people in real life”. This is why the information-theoretic argument ranks so low.
