Check with people from Argentina, Venezuela, anyone that lived in the 1980's Brazil, Ecuador, Turkey, Lebanon, Greece... see if they really think if relying on the State and their financial systems is a good idea.
What I don’t understand is why you go from not trusting the state to trusting a different currency which the state you don’t trust could just ban outright at any time.
Not trusting the State does not mean that the State is able to exert absolute control over people's lives. In fact, I'd say that the less trust the people have on the State, the more "illegal" activities people practice.
Personally, I'd tend towards air travel being a net positive, while Bitcoin is well into the negative.
