What happens if you take maximum cash advances from five credit cards and leave the US?

You would be charged with malicious criminal intent to defraud and other criminal charges. Which in the case of credit cards, is a Federal crime. And would come under the jurisdiction of the Attorney General and the FBI. FYI, I know personally of a man, who had no previous criminal record. And is now serving 25 yrs. in a federal penitentiary. No bull..just fact. How far they would go to track you down outside of the US, is anyone's guess. If you choose to "play such a dangerous game", don't plan on returning to the US. The minute your passport is checked, you will be placed in custody.
