The law is very mischevious. If you are born of an American abroad you are entitled to citizenship and that entitlement also means you are liable to American taxation. Moreover, there IS an exception from paying taxes (from here): If your income as a resident outside the US is less than $100K a year then you are not obliged to pay taxes.
You're an American National so have your obligation to pay your taxes, if you don't like it return to the US and pay taxes only here or stay in France and pay your taxes to both nations or renounce your citizenship and become a French National. As long as you hold dual citizenship you have to pay American taxes or have issues. The law is the law, and its unlikely to change for you anytime soon.
FATCA can change, because there are a LOT of millionaires who live/work in Europe - and must submit to FATCA because they are most certainly earning more than $100K a year. They could influence Donald Dork in the matter; and perhaps even persuade him to revoke FATCA. One thing is for sure - the EC will be revisiting the reasons for having agreed to convince the countries to accept FATCA ...
Our taxes are used to support our fellow citizens and government. It is a civic duty that transcends location. It is not about what your money to the government does for you. It is about what that money does for your fellow Americans. Your national parks, your poor, your military, your governmental institutions like the Library of Congress and NASA. A person living abroad still has their obligations to their home country. I am sorry LafayetteBis but I think you are very wrong in this. You have duty to your country as long as you keep citizenship.
