@Cr33pin that sucks to hear about Panama. I didn't expect the chaos to come there so soon.
I'm in MX and have residency here. Let me know if you have any specific questions but I'll provide some general insights.
Each state was left to their own judgment regarding restrictions. The feds stuck to this and hadn't required any testing or vaxx to enter from abroad. Mexico City hasn't had a mask mandate for a few months now but many people voluntarily wear them, even outside. Jalisco had vaxx passes but not sure how much it was enforced - I heard conflicting info. Nonetheless I don't see the locals dropping the masks anytime soon, they really have come to love the security theatre.
MX has/had a lot of freedom-minded people moving down. Mainly to the coastal areas such as Puerto Vallarta but there are small groups around the country. Some have co-ops of land and are working on food production. I'm in Telegram groups with the various freedom groups and see they organize weekly meetups and focus on solutions. They go around handing out flyers to locals in an attempt to wake them up about COVID, the vaxx, other stuff. I went to a freedom group meetup in central MX but unfortunately it was more of a Friday meetup for cigars and mezcal - not much organizing, buying land, working with ranchers/farmers.
Food production is much more localized and abundant given the size and biodiversity of the country. Food is plentiful (for now) and street vendors sell produce/nuts/eggs/etc. so even if they bring some vaxx pass to buy food one could still buy from these guys I imagine. The president recently visited some food production facilities and assured the people that they'd be putting in the dreaded price controls, so that signals that shortages are coming here too.
I often wonder if/when SHTF how that will look here, and how I'd be treated. They may only want to allocate food for natives first or something. I think well before then I'd head back to the US for a bit anyway though. Gringos are already a target though so figure what locals will do to feed their family.
I'm watching local news to see when things might start popping off. And then I'll regroup to the US for a bit or head to the coast where more expats are. That's loosely my plan.
Think just about every other LatAm country went full retard with the sickness. Several still require vaxx or test to enter. MX never had entry restrictions FWIW.
