Yup.

The billionaires' money is fundamentally only safe while the rule of law operates;

when contracts are fulfilled and options contracts are made good and short sellers obediently eat their losses and the bank gives you your money when you ask it.

Planning to take your money with you under conditions when it will cease to have any relevance as a concept is beyond fatuous - it would be poetic justice.

So the geniuses say you "buy assets" - like what? Seeds? Good gardening skills? Oil? Sharp Engine maintenance skillz?

We may find paper books and good teachers will be in high demand, then.

Because the real in-demand commodity will be civilization.
