Historically it seems likely that there will be several weeks or even months of warning where a reasonably prepared person can react. What sort of crisis would immediately or surprisingly close all borders? Coronavirus closed many borders, but we had many weeks to react before that. A significant challenge might not be leaving, but being accepted to another country.
Some practical and mostly cost-effective ideas that should increase the speed and odds of escape:
In the end, the two most important things are probably 1) having plans and 2) being ready to act on them. All of the others are nice but optional. Ultimately all that matters is that you exit.
inoculating via the GI tract, which may lead to weaker symptoms than the same load in the respiratory system.
A critical care doctor speculated in the This Week in Virology -podcast that getting the virus gastrointestinally might result in worse outcomes. They had observed that in hospitalized patients, those with GI symptoms tended to have worse outcomes, and one theory for why was that the GI system has the widest surface area for the virus to multiply in before spreading to the rest of the body. I don't have the expertise to judge how plausible this is.
Regarding point 2, how sure are you? Why are we even trying to disinfect N95 masks if that's true? I think your point is plausible but the filter technology in these masks isn't entirely trivial. Most filter materials actually depend on a static electric charge in the polypropylene to filter properly. Does the charge actually release the active virus particles after some time, and then you breathe them in? I have no idea. I was already surprised to find out that masks simply aren't just a dense material that filters particles, but a bit more complicated.
I bought a half-mask and several filters almost two months ago, and it's definitely easier and safer for my once-per-week shopping trip than a single use mask. I don't think that it's a particularly effective general solution though, for the following reasons:
1. All of these are sold out. To make more, you need to manufacture both masks and filters.
2. All the replaceable filters are sold out. The filters need to be sequentially rotated or otherwise disinfected.
3. Wearing one for anything more than 30 minutes is still quite awful.
4. Most of them have exhaust valves which still spread the virus to others.
Instead of creating new ingroups and outgroups and tribal signifiers for enforcing such, we should focus on careful truth-seeking. Some mythologies and terms that engage our more primal instincts can be useful, like when Scott introduced "Moloch", but others are much more likely harmful. "Orthodox vs Reform" seems like a purely harmful one, that is only useful for enforcing further division and tribal warfare.
To summarize, in this post Aaronson,
This seems like a powerful approach for waging ideological warfare. It is not constructive for truth-seeking.
