Because you treated cryptography as a field in its entirety. I think in practise that is how cryptography as a field works normally. Most secret messages communicated with crypto simply wouldn't be communicated (or just communicated in person) without the availibility of cryptography.
Even if the alternative is communicating in a way open to evesdropping i think there is still an intent requirement.
> Exactly at which point does the lie happen?
When there is intentionality to mislead (including by omission).
If you want to be really nitpicky, the definition i would give would be:
Taking (or failing to take) some action for the purpose of causing an adversary to have incorrect or incomplete beliefs that benefit you.
