I like how people often suggest to “just” open an account in a foreign bank.

Even assuming the foreign bank would not “just” refuse you for not being a resident, or being a significant risk, or not accepting your identification, or whatever. Then your Lebanese bank would surely wire the money there without any issues, and your Lebanese employer would be happy to do so as well, and of course there are no laws stating that only liras are legal payment currency for services rendered in Lebanon.

Of course. It would require prior preparation.

I have a few friends who worked in China and the default is you immediately move any money out of the country as soon as you can. It's simple to bring it in, but getting it out can range from "here are 5 forms to fill out" to "sorry, we aren't processing transfers at this time".

Or you can memorize 12 words. Not saying this should be the common practice or that everyone should do it, but having the ability to store your wealth in your mind is useful.

This feels like a parody, you don't store wealth in your mind otherwise you could create it out of thin air you merely keep track of your personal share of the world's wealth.
