Because I still have to file onerous US taxes, I can't open foreign bank accounts, and I personally would have to pay tens of thousands a year to the federal government even though they would do nothing for me while outside the US? I suspect you're wrong that $100k covers the majority of expats, but even if you are, it's not like it's much better to fuck over a minority of expats.
