So if a friend or family member from Europe wants to visit, they shouldn't travel with their personal laptops, phones etc? All this talk of 'keep your data on a private vpn server and ssh' is so far outside of what a normal person can do its ridiculous. I understand the concerns but 99.999999% of people aren't even aware of these things. And yet they can be arrested, detained indefinitely, and much much worse, for no reason whatsoever, and have their devices confiscated at the very least - and this isn't just a possibility now (as in its possible a black hole will spontaneously emerge and swallow us all) but a very likely probability. So what do we do? Not have any visitors, never travel?
