Renouncing US citizenship to get a bank account

You are correct about my health situation (both before and now with Obamacare). However, given the US pushing to make my life as difficult as possible overseas, I see no reason to give in and move back to the USA. In fact I have since lost my residency status in the Czech Republic (with a change of rules recently in the visa requirements).

Therefore I have to currently live as a perpetual tourist and move countries every 90 days as I did from 2002-2005. I have few assets in the USA, but it would be hard to live without a passport. I’d have to seek refugee status somewhere.
