Setting aside that Barbara is choosing to keep her US citizenship, renouncing it is actually very expensive. You have to travel to specific embassies, pay to have your US taxes current, and pay a fee over 2000USD which you do not get back if they deny you. You also need valid US identifying documents, which come with their own fees and travel costs. I’m not sure that trans people’s documents would be accepted any longer due to being “inaccurate”, but I don’t know the specifics to say for sure.
