That's fascinating. I was recently reflecting on how in 20 years Ill be telling young people "with a western passport, you used to be able to just book a flight and fly to almost any country you want and stay at least 30 days, but then covid happened." I'm so glad I got to do some nomad-ing for 2 years in my mid 20s. That level of openness is gone, and no the vaccine isn't bringing it fully back. The borders between The US, Mexico and Canada used to be a lot fuzzier too only 30 years ago. While there was SOME control, it was a lot more lax and after 9/11 it never came back. Once you give up some openness for security it never returns.
