This is a hallmark of having achieved comfortable familiarity within a system: You think you have total freedom because, mentally, you’ve excluded the off-limits things from consideration.

It reminds me of a couple jobs where management would tell us we had so much freedom that we could work on whatever we wanted. Choose your own destiny here! Except when you chose something that wasn’t among the short list of acceptable tasks, you were scolded for choosing something that was obviously not an option (to them). They knew the rules so deeply that the set of acceptable things seemed like the entire frontier of possibilities in their minds.

Like you said, it would be more helpful for everyone if the system actually clarified what was allowed and what was not so we didn’t have to guess. Drop the illusion of total freedom and replace it with clear rules that leave nothing to guessing.
