My "only half joking" premonition is that in a few years you're going to need a permit to travel outside the US. And I don't mean a passport. I mean an application that is either approved or denied each time you want to go somewhere. And if you dont stick to the approved itinerary (or you dont come back), feds come bring you back and charge you as a felon.

Each one of these border issues (phone passwords, checkpoints inside the US, travel bans) increases the total law enforcement "resistance" we face when traveling internationally. As the resistance increases, at what point does it become an "open circuit" ?
