So imagine this:
you owe X amount of money, and fleeing the country makes it vanish
Or you accidentally are given X amount of money, and fleeing the country is only way to keep it

Pulling out all your money or selling your home and possessions would give you away. And a pauper with a boat would be a red flag for any investigator. You’d have to be willing to give it all up. Your family would have to believe you died.
A better option would be to slowly siphon off money and be seen frequenting a casino, or become known as a drug addict. Once you’ve liquidated everything and racked up tons of debt, fake a suicide. Become aberrant or hyper-religious/political. Tell everyone that you’re going on a hike to “find yourself” or that you’re volunteering to fight in Ukraine. Never come back.
